While these were not bought at the York meet itself, they were bought on our York week travels. After the bandit meets on Wednesday, three of us Pgh. Hi-Railers drove up to Draude's Derailment train shop in Lebanon, PA where I found these:
Two covered hoppers and a PRR boxcar. Jim, the boxcar was one of yours as it had "Return to Westmoreland Glass, Grapeville, PA" markings on it.
