Look for the schematic on Nostalgia Air under United Moters Service - Delco.

Are you sure of that model number?

Before and after refinishing picture of mine:



I added the shading to match the original finish.

OK, I will look on nostalgiair. No, not 100% sure of the model number, that is what someone wrote on the back of the radio. Your radio looks real nice. I thought mine was the original finish, doesnt look like anyone has done anything to the cabinet, but like i say the edges arent really darker than the front like yours. Looks nice with the darker edges.

It might be the original finish. They weren't necessarily all the same or finished at the same time by the same guys.
