It is difficult these days to find these early 20th Century back plates in good condition. This one still has its beautiful copper finish. Because these plates are stamped steel with a thin copper plating, many of the ones we find have lost their plating. This back plate, with its small beaded edging, measures 6 3/4 inches long and 2 1/4 inches wide. The door knob hole center is 2 1/8 inches from the key hole. Screws will be included.
