Hi Lynn, According to the NCRS judging guide (6th edition):
Original front-brake backing plates are dull cadmium or zinc plated, while the rear backing plates are punched from a sheet of galvanized metal. The sheared edges are bare steel and may exhibit some rust on the edges. Later service replacement backing plates are a zinc dichromate finish.
