Vintage: Koken Barber Chair Serial Number List

1. Understanding Koken Serial Numbers

Koken (Koken Manufacturing Co., St. Louis, MO) did not maintain a fully public, linear date-to-serial-number list like an automobile manufacturer. However, based on factory records, patent dates, and collector crowdsourced data, approximate dating is possible.

Why You Should Document Your Serial Number

If you own a vintage Koken, do not rely on memory. Write down the serial number and stamp it into a piece of metal or wood attached to the chair's underside. vintage koken barber chair serial number list

• Insurance: If your shop is robbed or burns down, an appraiser needs the serial number to distinguish your $4,000 restored Koken from a $150 Chinese replica.
• Parts matching: Original hydraulic pumps are serialized to the base. If you swap parts, you destroy the historical value.
• Heritage: You are a steward of history. When you sell the chair in 20 years, the next owner will want that number.

Quick Reference: Identification Steps (ordered)

1. Locate and photograph serial/model/patent plates.
2. Note chair styling (Victorian vs. Art Deco vs. postwar).
3. Inspect hydraulics and base – document pump and casting details.
4. Search patent numbers and compare with catalogs/ads.
5. Use collector networks or specialists for confirmation.
