Colin and David,
Thanks for the suggestions. I could not find that IC car (by that number at least) in either my 1943 or 1953 ORERs. I found lots of GS and GB IC cars but no GRA. The IC car shows what looks like 6 drop door panels per side while the cars that came to the PGE had 4 hoppers per side. I will try contacting the Pre-Depression Era Railroad Modellers.
