When C&O and Erie 1937 AAR box cars with Viking roofs were repainted into the C&O for Progress and the larger diamond paint schemes were the black ends, roofs, trucks and underbodies repainted the same color as the rest of the car or did they remain black?
Walt, I can't answer your question about the C&O cars, but both new and repainted Erie box cars continued to have black roofs and ends for some years after the large diamond heralds were introduced - certainly well into the 1950s.
