This pair that dates from 1890 to 1920 is all cast brass and has the drop disc as a pull. The back plate is 1 3/8 inches round. The heavy brass drop is one inch round. The overall length of the pull from top of the back plate to the bottom of the drop is 2 1/2 inches. There is a hole in the back plate for fastening the plate with a brad or small screw so it will not twirl in place. These have not been cleaned but maintain their aged patina. Screws are included.
