When you find a serial number:
If you have ever run your fingers along the cast iron base of a vintage Koken barber chair, you have touched a piece of American industrial history. For over a century, the Koken Manufacturing Company—officially known as the Koken Barber Supply Co. (St. Louis, Missouri)—was the undisputed king of the barber chair. Their chairs were the Rolls Royces of the trade: heavy, hydraulic, and built to last several lifetimes.
Today, collectors, restoration experts, and vintage barbershops are on a constant hunt for these chairs. The single most common question asked in forums, Facebook groups, and antique stores is: “Where can I find a vintage Koken barber chair serial number list to date my chair?”
This article serves as the definitive resource on that topic. We will explore the reality of Koken’s serial number system, provide a practical guide to dating your chair without an official list, and explain why a complete “master list” likely does not exist.
⭐ 2.5/5 – A true “vintage Koken barber chair serial number list” does not exist in the way people hope. However, a combination of user-shared serials, patent dates, and physical features can reliably date your chair to within 5–10 years. If you need exact year verification, your best bet is a professional antique barber equipment appraiser (cost ~$50–100). Do not pay for a “secret serial list” – it’s a scam.
To identify the age of a vintage Koken barber chair, you can cross-reference the stamped serial number against known production runs. While exact annual records are rare, the following sequence provides a reliable ballpark for manufacturing years. Koken Barber Chair Serial Number Reference Serial Number Range Estimated Production Era Key Era Developments 10,000 – 25,000 c. 1895 – 1905 Introduction of first hydraulic models (1892 patent) 25,001 – 50,000 c. 1906 – 1915 Expansion into high-volume production 50,001 – 85,000 c. 1916 – 1925 Transition to ornate oak and cast iron designs 85,001 – 125,000 c. 1926 – 1935 Opening of the Koken Foundry (1926) for mass production 125,001 – 175,000 c. 1936 – 1945 Art Deco influence and wartime production shifts 175,001 – 225,000 c. 1946 – 1955 Post-war manufacturing before company closure 225,001 and higher c. 1956 – 1960s Final production before the Koken name was sold How to Find Your Serial Number
Underside of the Seat: This is the most common location. Look for numbers stamped directly onto the wood or the metal frame beneath the seat cushion.
The Base Casting: Check the iron base or the frame near the hydraulic mechanism for stamped digits.
The Footrest: Some chairs feature model numbers (e.g., "Aujusto") or patent dates (e.g., "1923") on the footrest, though these are often part identifiers rather than unique serials. Critical Dating Tips
Hydraulics vs. Manual: Koken patented the hydraulic lift in 1892. If your chair reclines but has no hydraulic system, it likely predates 1892.
Casting Numbers: Numbers like "52CB" or "527N" found on metal parts are usually model or part numbers, not serial numbers.
Materials: Early chairs (pre-1920s) often feature heavy wood carvings and ornate cast iron, while later models (1930s-50s) moved toward streamlined porcelain and enamel finishes.
For professional verification, you can consult specialized appraisers on platforms like JustAnswer or browse archival catalogs at the Missouri History Museum, which holds Koken records from 1887–1958. Determine Koken Chair Age by Serial Number - Expert Guide

If the serial number is missing or illegible, stylistic features can narrow the date:
Hydraulics: Chairs without a hydraulic lift system almost certainly date to before 1892, when Ernest Koken patented the hydraulic lift.
Materials: Early chairs (pre-1900) often feature carved oak or walnut. By the 1920s, white porcelain and chrome became standard.
Aesthetic: Look for Art Deco sharp lines for the 1920s–30s models, or more rounded, minimalist mid-century designs for the 1950s.

While there is no single, publicly accessible master "serial number list" for vintage Koken barber chairs today—as many factory records from the original St. Louis-based Koken Barbers Supply Company were lost when it went out of business in the 1950s—serial numbers remain the most reliable way to estimate a chair's production era when used alongside stylistic cues. Collectors typically cross-reference these numbers with known patent years and historical sales records to date their pieces. How to Find Your Koken Serial Number
Before you can date your chair, you must locate the stamped identifier. Koken typically placed these numbers in consistent locations:
Underside of the Seat Frame: This is the most common location. You may need to remove the seat cushion or flip the chair carefully to find a stamped number on the wood frame or the metal base plate.
Main Iron Base Casting: Many models have numbers molded directly into the cast iron of the base or near the hydraulic pump.
Metal Identification Tags: Some later models (circa 1920s–1930s) featured a small metal tag riveted to the frame under the seat or on the back of the footrest.
Note on Casting Numbers: Be careful not to confuse casting numbers (e.g., "52CB") with serial numbers. Casting numbers are part identifiers used during manufacturing and are shared by all chairs of that specific model, whereas serial numbers are unique sequential identifiers.

The following table provides ballpark production eras based on historical sequential logs and documented collector examples.

If you are struggling to find a 4-to-6 digit stamped number, check these common locations:
Under the Seat Plate: Most serial numbers are stamped directly into the metal framework or the underside of the wood seat.
The Pedestal Base: Inspect the vertical column near the floor plate.
Footrest Underside: Flip the footrest up; the number is often struck on the back plate.
Note: Raised numbers (like "52CB") are usually casting/part codes, not sequential serial numbers. Identifying by Design Features
Because serial lists are inexact, look for these physical clues mentioned in guides from LoveToKnow and JustAnswer:
Hydraulics: If the chair has a working hydraulic lift, it was likely manufactured after Ernest Koken's 1892 patent.
Materials: Wood-heavy frames (Oak/Walnut) with ornate carvings usually date to the late 1800s or early 1900s. Porcelain-coated cast iron became standard for the 1920s-1940s "white" look.
One-Lever Mechanism: Introduced around 1900, this allowed the barber to control all chair functions with a single lever.
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.
