FWIW, Here’s a new in the sealed box(picture of box) purchase of the Penn Red Arrow cars I wanted for a Tuscan K4. Beautiful cars. Zinc pest. Had to buy six new trucks that were from the half price sale in Concord. Another $75 plus shipping, The diner was the same way, another two trucks, + ship. Sellers were accomodating to a certain extent, but how do you ever know? Perhaps I was not as knowledgeable of the condition during these model years that it was a problem.
