I've read about other Browning King & Co. buttons but haven't found one with a "K" on it. I know they made uniforms for train conductors and military, etc. Any help would be appreciated.
"Browning, King & Co. of NYC and Chicago dealt in clothing and uniforms from around 1860 to at least 1934 and were listed in Chicago until at least 1888. This two-piece button was most likely made by Scovill. Browning King & Co evolved from earlier browning firms located in NYC during the Civil War. This back mark was used from 1860-1934."
