I have 2 wooden arm chairs. The back of the chair reclines slightly. A brass plate on the back of the chair says 'Richards Panel Chair, Pat'd 9'82, 8'90, 7'92, 7'02. I know the chairs are pre 1930's. The family always called them the barber chairs. I would like to find out more information about them. Any info on the manfacture, what they were used for, etc.
