Vintage Koken Barber Chair Serial Number List ^new^ -

I was unable to locate a single, comprehensive, or official “vintage Koken barber chair serial number list” that you can simply download or search by number. Here’s an honest review of what actually exists and how to work with Koken serial numbers.

• Serial Style: Usually lower numbers, often 1 to 4 digits.
• Patent Dates: Look for dates like Oct. 23, 1900, June 9, 1908, or Nov. 1912.
• Estimate: If the latest patent date on your chair is 1908, your chair was manufactured no earlier than 1908, likely within a 2-5 year window after that date.

• Serial Style: 4 to 5 digits.
• Identification: Look for model numbers cast into the metal. The "No. 11" (plain base) and "No. 12" (ornate base) were incredibly popular.
• Serial Range: Numbers in the 10,000 to 50,000 range often align with this era.

While no complete master list exists, experts at platforms like JustAnswer Antiques and collector communities use these general benchmarks: Serial Number Range Estimated Era Key Innovation 1881 – 1884 First reclining chair patents. 1,000 – 9,999 1885 – 1891 Swiveling and reclining mechanisms introduced. 10,000 – 40,000 1892 – 1900 The introduction of the first hydraulic lift Early 1900s – 1920s High-production era after the Koken Foundry expansion.
