Revell did the Valiant wagon in 1/87 scale back in the early 60's. There are 1/87 scale resin kits available for a 64 Ford Country Squire wagon and a 65 Valiant wagon by 87RPM Models (a one person operation in Berlin, Germany. I have some of the 87RPM kits and have ordered the 1/87 scale 64 Squire and 65 Valiant wagon. But, I need to improve my painting skills before I build the kits.
I had that Val wagon, plus, IIRC, there were three or four other Chryslers in a set. I had them back in college, but, as what parents do to their kids, a bunch of boxes of my stuff I DID NOT WANT SOLD were opened up by Mom right after I had left for the Navy. I've never seen that set anywhere since.
I honestly just wish someone would make inexpensive but fairly-well-detailed HO scale car models of all types, so as to make railcar loads, as well as the Evans Autoloader gear for the forty and fifty-foot automobile boxcars.
