Dating a Morris guitar by its serial number is notoriously tricky because the Japanese manufacturer, Moridaira, used several inconsistent systems across different eras and factories. Unlike brands like Fender or Gibson, there is no single "master list" that covers every model. 1. Where to Find the Serial Number
The Neck Block: Most Morris acoustic guitars have a serial number stamped on the wooden block where the neck meets the body, visible by looking through the soundhole.
The Paper Label: Some models feature the serial number printed on the internal paper label, which also lists the model name (e.g., W-40).
Back of the Headstock: On certain electric or later acoustic models, you might find a stamped number or a "Made in Japan" sticker with a serial number on the back of the headstock. 2. Common Serialization Patterns
While inconsistent, you can often decode the age using these common formats:
The 6-Digit Format: Common in the 1970s and 80s (e.g., 852554). The first one or two digits often represent the year. For instance, a number starting with "7" or "75" typically indicates a 1975 build.
Internal Date Stamps: Some models have a separate, simpler 6-digit stamp on the neck block (e.g., 062501). This is often a direct date: June 25, 2001. Decade-Based Labels:
Early 1970s: Labels often featured "Yoshino Musical Instruments" or older circular designs. Late 1970s/1980s: Standard "Morris" rectangle labels.
Modern (2001–Present): Serial numbers are more standardized and can often be verified by contacting Morris Guitars directly. 3. Using Model Numbers to Estimate Age
If the serial number is missing or unreadable, the model number can provide a range:
The "W" and "M" Series: Standard dreadnoughts and 000-style guitars. A model like the " Go to product viewer dialog for this item. " likely cost 40,000 Yen when new.
Production Shifts: Morris guitars were primarily made in Japan from 1967–1980, then production shifted to Korea for mid-range models, before returning high-end production to Japan in 2001. 4. Expert & Catalog Resources
Because official databases are limited, comparing your guitar to old catalogs is often the most accurate method:
Catalog Archives: Sites like Vintage Japan Guitars host digital scans of Morris catalogs from 1970 through 1980.
Direct Inquiry: For modern instruments, you can download the latest official Morris Catalog PDF to check specs and serial formats for new series. Dave Doll's Pro Tips - Serialization and Registration
Morris guitar serial numbers are essential for dating and authenticating these Japanese-made instruments, which have been produced by the Moridaira company since 1967. Because the brand has undergone multiple production eras and used various labeling systems, deciphering a serial number requires looking at both its format and its location. Where to Find the Number
The location of a Morris serial number often depends on whether it is an acoustic or electric model:
Acoustic Guitars: Typically found on a paper label inside the soundhole or stamped directly onto the neck block (the wooden block where the neck joins the body).
Electric Guitars: Most often located on the back of the headstock or on the neck plate where the neck bolts to the body.
Vintage Models: Early models from the late 1960s to early 1970s may have handwritten dates or no serial number at all, as many Japanese brands did not adopt consistent serialization until the mid-1970s. Common Deciphering Patterns
While Morris does not have a single, universal database for all eras, many of their serial numbers follow standard Japanese manufacturing logic: 1. The 6-Digit Code
This is common on many Japanese guitars from the 1970s and 1980s.
First Two Digits: Usually indicate the year of manufacture (e.g., "78xxxx" likely indicates 1978).
Remaining Digits: Often represent the month and production sequence. 2. Model Prefixes and Series
Morris used specific prefixes that help categorize the instrument, which is vital when the serial number alone is ambiguous: W Series: Standard dreadnought models (e.g., W-18, W-50). TF Series: High-end models produced in the 1980s.
S Series: Modern high-end "made for fingerpickers" models introduced from 2001 onward. 3. Signature Labels
Some Morris acoustics feature labels signed by specific luthiers or master craftsmen. For example, some high-end vintage models may have signatures that appear below the serial number, adding to the guitar's collectible value. Historical Context and Authenticity
The name "Morris" itself comes from founder Toshio Moridaira's nickname, given to him by an employee at the Gibson factory in 1964. Because Morris produced everything from affordable entry-level guitars to professional-grade instruments, serial numbers are the primary way for collectors to verify if a guitar was "Made in Japan" at the famous Nagano factory.
💡 Key Tip: If a serial number is faded or missing, you can often narrow down the production year by cross-referencing the guitar's features (like bridge style or headstock logo) with original Morris Guitars Catalogues.
If you tell me the serial number or model number (like W-40 or TF-80) on your guitar: I can look for catalog specs to see what woods were used.
Morris guitar serial numbers are primarily used to identify the production year and factory of origin, though formats vary significantly based on the era of manufacture. Most Morris guitars were produced in Japan by the Moridaira factory, with some production moving to Korea in the mid-1980s before returning to Japan for modern high-end models. Common Serial Number Locations
Neck Block: Stamped directly onto the wood block inside the soundhole where the neck meets the body.
Paper Label: Printed on a label visible through the soundhole. Headstock: Stamped or printed on the back of the headstock. How to Decode Morris Serial Numbers
Because Morris has used multiple numbering schemes over decades, decoding often requires looking at the first few digits or combining the serial with the model name. 1. 6-Digit Formats (Vintage Japanese Models)
Many 1970s and 1980s Japanese-made Morris guitars use a 6-digit system.
Dating a vintage Morris guitar can be tricky because the company, founded by Toshio Moridaira
in 1967, changed its numbering systems multiple times across different decades. While there is no universal "decoder" that works for every model, you can usually narrow down the year using the following logic based on the serial's structure and label design. 1. The Most Common 6-Digit System (1970s–1980s)
The most frequent serial number format found on Japanese-made Morris acoustics from the "Golden Era" uses six digits, often stamped on the back of the headstock or printed on the interior label. (Year, Month, Sequence) or (Year, Sequence) A serial starting with would typically indicate a production year. Decade Clue: If the number starts with 0, 1, or 2 , it is likely from the for 1981). 2. Identifying by Series and Model Name
Because serial numbers were sometimes "chaotic" or absent on lower-end models, collectors often use model prefixes and catalog shifts to date their instruments: W-Series (1970s):
Early dreadnought copies (like the W-30 or W-50) often have 6-digit serials. Many transitioned to new naming conventions in the early 1980s. TF-Series (1980s):
High-end models (e.g., TF-50, TF-80) began appearing in catalogs around 1980–1983. If your guitar has a prefix, it is almost certainly from 1983 or later. Tornado Series (1978–1980s):
These thin-body acoustic-electrics, inspired by Ovation designs, were introduced in 1978. www.morris-guitar.com 3. Visual & Hardware Clues
If the serial number is missing or illegible, look for these design changes: Logo Style: morris guitar serial numbers
Early 1970s models often used a "vertical" logo similar to Martin guitars, while late 1970s and 1980s models moved toward a more stylized "M" or cursive script. Internal Label: Blue/Orange labels: Common in the early-to-mid 1970s. Black/White or Gold labels: More frequent in the 1980s. Bridge Type: In the 1980s, specialty models like the used various bridge types that varied by year. 4. Recent Production (2001–Present) What year is my Morris/Mori Dira Hurricane guitar?
Decoding the serial numbers on Morris guitars is a journey through the evolution of Japanese lutherie. While the company (Morris Gakki) is celebrated for its craftsmanship, their historical serial numbering systems are famously inconsistent, often shifting as the brand grew from a small workshop to a high-volume exporter during the "lawsuit era" of the 1970s and 80s Finding the Serial Number
On a Morris guitar, the serial number and model designation are typically found in three locations: The Paper Label
: Visible through the soundhole, often containing the model name (e.g., W-40, TF-50) and a numeric sequence. The Neck Block
: Stamped into the wood at the base of the neck inside the guitar. The Headstock
: Older models or specific export runs may have a stamp on the back of the headstock. Decoding Logic
Identifying the exact year of a Morris guitar involves several distinct patterns based on the era of production: Numerical Dates (The Six-Digit System)
: Many mid-period Morris guitars use a six-digit code that corresponds to a date (DDMMYY). For example, a stamp of translates to June 25, 2001. Year-Prefix Systems
: Some series use the first two digits to indicate the year. A serial starting with often points to 1983 or 1985 respectively. The "Terada" and "Iida" Variation
: Morris outsourced some manufacturing to the Terada or Iida factories. These often followed factory-specific sequences rather than a unified Morris system, which can make identification difficult without cross-referencing factory logs. The Signature Era
: High-end vintage models were often inspected and signed by master luthiers like Ryoji Matsuoka
. A signature on the label is frequently a better indicator of a guitar's quality and vintage (late 60s to mid-70s) than the serial number itself. Key Identification Markers
: The "Vertical Morris" logo (similar to Martin's) generally denotes 1970s production, while later models might feature more modern, stylized scripts. Made in Japan Sticker
: Most vintage Morris guitars will feature a "Made in Japan" sticker or stamp, confirming their origin during the peak era of Japanese acoustic production.

Title: Cracking the Code: Why Morris Guitar Serial Numbers Are a Folk Musician’s Treasure Map
If you’ve ever held a vintage Morris guitar—perhaps a humble W-15 or a pristine B-50—you’ve likely flipped it over, squinted at the faded stamp on the neck block, and asked the same question: Where did you actually come from?
Unlike the linear, spreadsheet-friendly serial numbers of Martin or Gibson, Morris serial numbers are a wonderfully cryptic rabbit hole. And for the folk and bluegrass enthusiast, learning to read them isn't just nerdy trivia—it's the key to understanding one of the most underrated "lawsuit era" gems.
The Mystery of the 1970s "Black Label"
The most interesting part of the Morris story lives in the early 1970s. During the Japanese "lawsuit era," Morris guitars (made by the Moridaira Corporation) were so impeccably crafted that they rivaled Martin D-28s at a third of the price. Their serial numbers from this period are short—often just 4 to 6 digits—and utterly non-standardized. You might find a "3050" on a neck block and assume it's a low production number. Wrong. In many cases, the first digit indicates the year of the Japanese fiscal year, not the calendar year. A "3" could mean 1973... or late 1972.
This ambiguity is actually part of the charm. Veteran collectors have built entire forums around decoding these numbers through secondary features: the shape of the "M" logo, the type of tuning machines, or the infamous "Lawsuit" headstock shape. Your serial number isn't a receipt; it's a clue.
The Transition (Mid-80s to 90s)
As Morris moved away from Martin copies and into their own beautiful, asymmetrical designs (think the "Morris Fan-Fret" or the "B-500"), the serial numbers got smarter. By the late 80s, you typically see a six or seven-digit system: YYMMXXXX.
For example: 8704156
Suddenly, you aren't just looking at a number. You are looking at a birthdate. You know your guitar was built alongside the very first Takamines and Yamahas that would go on to dominate the world stage. It feels personal.
The "No Number" Phenomenon
Here is the most interesting (and frustrating) review point: Not all Morris guitars have useful serial numbers.
If you find a Morris with no serial number at all, or a blank stamp, do not assume it is a fake. During the late 70s export boom, Morris produced "seconds" and "store-brand" models (sold as "Conrad" or "Kingston") that were mechanically identical but lacked internal serialization to avoid brand-dilution. These "ghost" guitars often sound better than their numbered siblings because they were made by the same luthiers on a Friday afternoon with leftover premium woods.
The Verdict
Reviewing Morris serial numbers is not like reviewing a computer database. It is like reading faded calligraphy. You will not get a clean CSV export. You will get a headache, a magnifying glass, and eventually, a deep respect for a brand that prioritized craftsmanship over bureaucracy.
If you want to know the exact factory shift your D-18 copy was made? Buy a Martin. But if you want a story—a mystery that connects you to the hidden history of Japanese luthiery from 1972 to 1995—dig into those faded digits on a Morris. Just be prepared to argue with strangers on internet forums about what that "4" really means.

Dating a Morris guitar by its serial number can be challenging because the company, founded in Nagano, Japan in 1967, used several inconsistent systems throughout its history. Unlike major brands with standardized databases, Morris often changed its serialization based on the factory or production era. Finding Your Serial Number
The location of the serial number on a Morris guitar depends on its type and age:
Acoustic Guitars: Look for a paper label visible through the soundhole or a number stamped on the neck block (the wood inside where the neck joins the body).
Electric Guitars: Serial numbers are typically stamped into the back of the headstock or on the neck plate where the neck bolts to the body. Decoding Common Patterns
While no single "master key" exists, many Japanese-made guitars from this era follow these general logic patterns:
Year-First System: Often, the first two digits indicate the year of manufacture (e.g., a number starting with "75" likely means 1975).
Decade Prefixes: Some models use a letter to signify the decade (e.g., "S" for 1970s), though this is more common in US-made instruments and only appeared on specific export Morris models.
Short Sequences: Early "lawsuit era" models (1970s) may have very short 4-digit serial numbers that represent a simple production sequence rather than a date. Dating a Morris guitar by its serial number
Decoding Morris guitar serial numbers requires understanding the company's evolution from a 1960s Japanese workshop to a premier fingerstyle brand. Because Morris (founded by Toshio "Mori" Moridaira in 1967) has used various numbering systems over the decades, identifying the era of your instrument is the first step toward dating it Blue Book of Guitar Values 1. Identifying the Era of Your Morris Guitar
Before checking the serial number, look for these physical clues to narrow down the timeframe: The "Golden Era" (1960s–1970s):
These are often Martin or Gibson copies. Labels typically feature the "Moridaira" or "Morris" name with a stylized logo. Early serial numbers are often short (4–6 digits) and stamped on the neck block or a paper label inside the soundhole. The "Tornado" Era (Late 1970s–1980s):
This period introduced thin-body acoustic-electrics inspired by Ovation. Instruments from this time often feature a silver serial-number sticker on the back of the headstock. Modern Era (2001–Present):
Known for the "S Series," these guitars are "Made for Fingerpickers." Serial numbers from this period are often more standardized, sometimes following a Date-Specific Format www.morris-guitar.com 2. Common Serial Number Formats
While Morris did not always use a single consistent system, several patterns emerge from collector data: Date-Encoded Formats (Modern & Some Vintage): Some 6-digit stamps (e.g., ) can be read as . In the example , the date corresponds to June 25, 2001 Sequential Numbering (Early Models):
Many 1960s and 70s models used simple sequential numbers (e.g.,
) that do not explicitly contain the date. To date these, you must cross-reference the Model Number (like W-18 or A-12) with Vintage Morris Guitar Catalogs Sticker Prefixes (1980s):
Guitars from the early 1980s may have a silver sticker with a letter/number prefix. While less documented than brands like Fender, these stickers are unique markers of Moridaira factory production during that decade. 3. Where to Find the Information Soundhole Label:
Most acoustic models have a paper label visible through the soundhole. Neck Block:
Look inside the soundhole toward the neck; numbers are often stamped directly into the wood. Back of Headstock:
Common for 1980s electric and acoustic-electric "Tornado" models. Neck Plate:
For rare Morris electric guitars, check the metal plate where the neck joins the body. 4. Verification & Valuation Tips
Because serial numbers can be hard to read or inconsistent, use these supplementary methods to verify your guitar's age: Construction Details:
Check for features like adjustable bridges (common in the 70s) or specific "Abalone" borders. Historical Milestones:
Morris entered the U.S. market in 1974 and re-entered in 2001. If your guitar has a "Made in Japan" sticker and was bought in the U.S., it likely falls into one of these two windows.

Understanding Morris Guitar Serial Numbers: The Ultimate Dating Guide
Morris Guitars, founded by Toshio "Mori" Moridaira in 1967, are legendary for their high-quality Japanese craftsmanship. Whether you own a vintage "lawsuit era" Martin copy or a modern fingerstyle masterpiece, decoding the serial number is the first step in uncovering your instrument’s history. Where to Find Your Morris Serial Number
Unlike many mass-produced brands, Morris serial numbers can be found in several locations depending on the era and model:
The Paper Label: Most commonly, the serial number is printed on the label visible through the soundhole.
The Neck Block: On many older models, look inside the soundhole toward the neck; the number may be stamped directly onto the wooden block.
Back of the Headstock: Some electric models (like the Hurricane series) and later acoustics have serial numbers stamped or stickered here.
The Neck Plate: For Morris electric guitars, the serial number is often found on the metal plate where the neck joins the body. Decoding the Numbers by Era
Morris serialization has changed over decades, moving from simple sequential numbers to date-coded systems. 1. The Early Years (Late 1960s – Mid-1970s)
In this era, serial numbers were often simple sequential digits (e.g., 4 or 5 digits) that tracked total production. These are difficult to date precisely without checking official Morris Guitar Catalogues.
Key Indicator: A label that says "Yoshino Musical Instruments" (pre-1972) or "Maurice Musical Instruments" (post-1972). 2. The Golden Era (Late 1970s – 1980s)
During the peak of the Japanese "Copy Era," Morris began using more structured codes. Many follow a pattern where the first one or two digits represent the year.
First Two Digits = Year: For example, a serial starting with "79" typically indicates 1979.
6-Digit Formats: Often formatted as YYMMXX (Year, Month, Production Number).
Example: 810522 would likely be the 22nd guitar made in May 1981. 3. Modern Era (2001 – Present)
When Morris re-entered the U.S. market in 2001 with the "S Series," they modernized their tracking.
9-Digit Codes: Similar to Taylor or other modern makers, these may include series codes and production dates.
Check the Label: Modern handcrafted models often have the date explicitly written or coded on the label. Understanding Morris Model Numbers
Model numbers are often more useful for dating than the serial number itself. Morris used a letter-prefix system: W-Series: Dreadnought models (Martin-style). F-Series: Smaller "000" or Folk-style bodies.
TF-Series: "Tashio Fender" or higher-end acoustic-electric lines. B-Series: 12-string models (e.g., B-25, B-50).
Tornado: Thin-body acoustic-electrics with Ovation-style backs. Pro-Tip: The Potentiometer Trick
If your Morris is an electric model and the serial number is missing, you can date it by checking the potentiometers (volume/tone knobs). Open the back control plate. Look for a 7-digit code (e.g., 1378042).
The 4th and 5th digits usually indicate the year (80 = 1980).

If you’ve recently acquired a vintage Morris guitar, you likely know you’re holding a piece of Japanese luthiery history. Founded in 1967 by Toshio Moridaira, Morris (Moridaira) Guitars became a cornerstone of the "lawsuit era," producing high-quality Martin and Gibson replicas before developing their own unique lines like the Tornado and S-series.
However, dating these instruments can be notoriously tricky because Morris used several different serialization systems across their factories in Matsumoto and overseas. Here is how to decode Morris guitar serial numbers and identify your guitar's age. 1. The Standard 6-Digit Code (1970s–1980s)
The most common serial format for 1970s and early 80s "W-series" (Martin style) and "F-series" (folk style) guitars is a six-digit number usually found on the internal neck block or the back of the headstock. Format: YYXXXX
How to read it: The first two digits typically represent the year of manufacture.
Example: A serial number starting with 75 (e.g., 750421) indicates the guitar was made in 1975.
Note: Some models from the late 70s used a YXXXXX format where only the first digit indicated the year (e.g., 8XXXXX for 1978). 2. The Letter-Prefix System (Special & Export Models)
For certain export lines and specific mid-80s models like the Morris Hurricane or higher-end TF series, you may find a letter preceding the numbers.
A, B, or C Prefixes: Often denote the production month or the specific factory line.
Dating: Even with a letter, the next two digits usually follow the year format. For example, 83 after a letter often confirms a 1983 build date. 3. Labels and Logos: The Non-Serial Clues
If your serial number is faded or missing, the physical appointments of the guitar are your best dating tools. Morris changed their label designs and logos frequently, which can narrow down the era:
Blue/Green Labels (Late 1960s – Early 1970s): These are the earliest mass-produced models, often featuring "Moridaira" or "Morris" in a simple script.
Square Black/Gold Labels (Mid-1970s): Found on many of the high-quality Martin clones (W-25, W-40, W-50).
The "TF" Era (1980s): Around 1983, Morris rebranded many "W" models to the TF series . If your guitar is a TF-80, it was almost certainly made after 1982.
Vertical "Morris" Headstock Logo: This Martin-style vertical logo was most prominent during the mid-to-late 1970s "lawsuit" peak. 4. Modern S-Series and Hand-Made Models (2001–Present)
Modern Morris guitars, particularly the fingerstyle-focused S-Series, use a more formalized numbering system. Format: YYMMXXX
How to read it: The first two digits are the year, the next two are the month, followed by a production sequence number.
Check: Look for "Luthier Made" or "Hand Made" stamps, which indicate the guitar came from the premium workshop rather than the standard production line. Summary Table: Morris Dating Quick-Reference Likely Serial Format Label/Logo Style 1967–1972 No serial or 4-digit Blue or Round "Moridaira" labels 1973–1979 6-digits (starts with 7) Black/White labels; Martin-style logos 1980–1989 6-digits or Letter prefix "TF" or "Hurricane" branding appears 2001–Now 7+ digits (YYMM...) S-Series for fingerstyle; Hand-Made Premium labels
Do you have a specific serial number or a photo of the label color? Knowing the model number (like W-40 or TF-25) can also help pin down the exact catalog year.
