Not sure which PRR car you are talking about but the "PS-1" boxcar,

has already been pointed out is more like a 1937 AAR car, it's

BOGUS. It is numbered and labeled as an X29. The X29 would never be

with anything else. The PRR had NO AAR 1937 boxcars. As for the USRA
hopper, the Pennsy had 300 in 1920, and 30 were left in 1955. Unless

modeling the Pennsy in the 1920's you probably don't even need one.
