I have a few BAR questions, please, keep it simple, I do not know much about trains but I have a few things that my uncle brought me when he was tearing apart BAR loco's and cars. The first is a log book, it is from BAR 70, can anyone tel me what BAR 70 was, was it an F or something else? The other are a couple of pictures BAR 502 was an F what? Uh I think that that is it for now.
