I'm new to both these forums and model railroading in general. I'm looking for some advice on modeling some covered hoppers that will be used to transport both grain and raw materials for a concrete factory. Specifically I'm look for advise on the color scheme that would have been used on these cars in the 1930's. Obviously most of the pictures I'm finding of prototypes from that era are black and white. The color seem to be an oxide red. Can anyone confirm that? Any suggestions on brands/colors of paints to use? Thanks in advance for any help.
