This beautiful very early pair has the filigree brass back plate and the disc drop made out of cast brass. These would polish up to be very shiny, but we have left the old patina as is. The back plate is 1 3/8 inches round, and the drop disc is also 1 3/8 inches round. The overall length of the pulls are 2 3/4 inches. One doesn’t find pulls much finer than these. Screws are included.
