I don't know, I see it pretty often - when I go to Pete's place or he comes to a meet near here! Seriously, that was an ambulance at a coal mine in PA, and it was garaged all it's life and had only around 6,000 miles on it when they finally sold it in the early-'90's!!!! Truthfully, it had never been used. The only thing they replaced - ever - was the fuel pump. It even had it's original tires! Dad and I actually went up to look at it, and submitted a closed bid on it. We were outbid by Pete, the only other bidder. He added the "East End" lettering.
When they sold it, it even had all the original first aid supplies in the cabinets.
