Sorry, I just looked at your pictures again, there really is a metal backing plate or mask behind the dial, that makes things easy. I though it was some sort of metalic back paint like most dials from then seem to have. I would go on the hunt for some suitable bronze or brown metalic spray paint, and primer, strip the old paint and rust off, and start over.
