I recently just picked up a theo a kochs barber chair for $50. Im trying to find out what year it is and just general information about the company. Ive scoured the internet and couldnt find much. I havent searched for serial numbers yet but on the back rest, theres a plate that has patent years. The newest is July 7, 1914 and the oldest is May 10, 1910. Also on the neckrest, there is a little thin tube and on the front im pretty sure it says Universal october 1909. Im not sure if this is the patent on the neckrest or what. Im pretty excited about this find. If anybody can please help me with reaources or some gen info that would be awesome! Thanks!
