Btw Tom, the track was a mic of black rail and shiney as from two seperate sets and the 716 dump had the early center trip on the truck. The 322 has no buttons on the chassis, no pins in the rims, I don't see a date stamp in the cab yet. The cab number is not block and you can see the couplers for comparison below. I am not sure if it is thivk or thin shank. I'm curious as to your thoughts on 46 or 47 on this one. I don't really care, just curious.
