Hey all you scratchbuilders, I'm about to give it a shot. Actually, I want to model a local factory, photo attached. It was built as a silk mill, later a womans purse factoty, currently warehouse space for an old time auto parts dealer. It didn't have rail service. I like the building and will model the main building fairly closely, but will be adding rail service. Since I want it to be a ball bearing mfr., and I know nothing about their manufacture, I thought I'd seek info here. I'm guessing they use steel rod? If do, I'll deliver it on 40' flatcars. I suppose a crane would be used to unload? How wide should the freight doors on the bldg. be? Anyone have pertinant photos?
