I'm working on a group of covered hoppers from 1920s - 1957 (B&O). I seem to remember an article in one of the model magazines from a number of years back that discussed using white pepper to simulate grain spilled on top of the covered hopper and paint masks for something. Does anyone know when/what magazine this could have been? I have looked through everything I have and can't find it.
Since y'all are the smartest, I figured it couldn't hurt to ask here.
thanks and keep up the great chats
