When I painted my original 1940 1/2 ton engine, I bought paint from Jim Carter that claimed to be the correct color. When I painted the engine for my 53 half ton, I bought PPG paint using the number code that I got somewhere on this site. Both paints are gray, but the PPG paint is darker gray than the paint from Carter. I don't particularly care, I just thought I'd share that in case it could help anyone.
