Inquiry (采购产品): Antique Office Chair Sorry to bother you, but I have been trying to date a very old wooden office chair I have. The only identifier I can find is stamped on the metal device that controls the height and spring action of the chair. "BETTCHER CLEVE PAT 7-15-24" My guess is that Bettcher may not have made the whole chair, but perhaps just this piece. The casters on it (original) have a company name that seems to have existed in Long Beach California between 1921 and 1929. Can you confirm any of this? Thanks in advance for any reply.
