This unusual pair of hinges date to around 1900 to 1920s. They had a flashed copper finish originally, but now some of the flashing has rubbed off. They are steel based.
The hinges can be used flat on the surface of a cabinet or mortised into the wood with only the spine showing.
The short wings on this pair measures 1 3/4 inches vertically and 1/2 inch wide (or horizontally). The wider rounded wings is 1 1/2 inches vertically and one inch horizontally.
The pair is in very good shape and loose at the spine. Screws will be included.
