Vintage Koken Barber Chair Serial Number List ~upd~ May 2026

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.

Identifying the age of a vintage Koken barber chair is typically done by cross-referencing its stamped serial number with documented factory production ranges. These numbers were logged sequentially, providing a reliable—if approximate—indicator of the manufacturing year. While serial numbers are the primary tool, you should also look for casting numbers (like "52CB") or patent dates molded into the iron parts, as these help confirm the model and production era.

Where to Find the Numbers

Under the Seat: The most common location is stamped on the underside of the seat frame or on the wood under the cushion.

The Base: Check the iron base casting or the metal plate where the chair connects to the hydraulic pump.

Footrests: Sometimes "Koken" and model/part numbers are cast directly into the ornate metal footrest. Visual Clues for Dating

If the serial number is missing or illegible, stylistic features can narrow the date: While there is no single, publicly accessible master

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.
