How would one go about finding out what color something was when new? An example would be the hood hinges and springs on my truck. They were put on after the body was painted. Things like bolts, brackets, rotor hubs (4X4), door hinges, etc. I’m rebuilding a 1978 F-250. While I have to clean, de-rust and paint everything I thought it to be nice if I could paint it like it was when new. I have no idea of where to look for such info. Looking at pictures of un-restored trucks (if you can find them) only helps so much (or little) as most have lost the coating and have a coat or rust or gunk on them.
