Does anyone know what parts on an ATC70 were gold plated and what was silver plated. I have a resto going and am not sure? The pics below show some parts that are no doubt gold and some silver but a few look like they were silver from the factory but over time turned a bit gold?? For example I know the brake return spring is gold but the brake cam is not so obvious? The last pic is after I plated some brake parts. The only thing I can think of to determine if it was a gold part is to look at nos oem parts on ebay. Is there any other ways you could recommend?? Thank you John
