Not bad Dave-as kind of a RBOX aficionado I'd have to say you were pretty much spot on as
to fade that car. While the bottom sill of the model isn't correct for the type of car it's supposed
to represent (& I know you don't care) but it's supposed to be a Golden Tye built Railbox according
to the #, & one the types that actually faded, instead of becoming a more golden brown color.
The Golden Tyes, along with the USRM & Berwick built, have all by now mostly faded to a sickly
yellow as opposed to the ACFs, PS's, & FMCs.
So if you're shooting for your era of 1980, well you pretty much hit it! ;D
