This simple, but elegant, pair of flashed copper back plates date from 1900 to the 1920s. The pair appear to have very little wear. The flashing is like new. The popular finish of that era was a coat of copper applied to steel plates, then flashed (or sprayed) with a black lacquer. Because of this process, no two pieces are identical.
Each back plate measures 7 inches vertically and 2 1/2 inches across. The width of the plate at the door-knob level is 2 5/8 inches. The distance between the door knob hole and the key hole is 2 1/4 inches. The diameter of the door knob hole (door knob neck) is 5/8 inch.
Screws will be included.
