List — Vintage Koken Barber Chair Serial Number

This is a challenging request because Koken Barber Supply Company did not publish a single, public "master list" linking specific serial numbers to exact manufacturing dates. They were a private company with proprietary records, and many of those historical records were lost or discarded over time.

However, I have compiled a "Field Guide" to dating your Koken chair. This uses the serial number in conjunction with physical features (patents, motors, and tags) to pinpoint the age.

Here is a useful piece for identifying and dating your vintage Koken barber chair.

Let’s address the elephant in the restoration garage immediately. There is no publicly available, comprehensive, decade-by-decade “Koken barber chair serial number list” like you would find for a classic car or a Winchester rifle.

Why? Unlike firearm manufacturers who kept meticulous, surviving logs for liability reasons, Koken was a supply company. While they stamped serial numbers on their chairs (usually on the hydraulic pump housing or the base plate), the original factory ledgers have been lost, destroyed, or are locked in private collections that have not been digitized. vintage koken barber chair serial number list

What does exist? What collectors call a “list” is actually a patchwork of crowd-sourced data, original catalog reprints, and a few key serial number ranges recovered from surviving shipping ledgers from the early 1900s.

Why Koken Chairs Matter

Founded in 1902 by Charles Koken, the company revolutionized the industry by introducing the hydraulic lift mechanism. Before Koken, barber chairs were often clumsy and manually cranked. Koken brought luxury, durability, and engineering prowess to the barbershop. Because they were built like tanks, thousands survive today, but identifying the exact year of manufacture requires some detective work.
