I picked up an ancient kit from an internet seller and low and behold the box held two full kits. Alas, the two kits were from Fort from back in the early 90s. I think they are now Eastern Express molds if they are still kitting them. I believe Miniart, Zvezda, and Hobby Boss make some version or another but I could stand to be corrected on that.
The two I put together went together surprisingly easy with only small fit issues here and there. I'm not going to comment on scale thickness or anything of that sort; you can probably figure out what that was like! Some of the detail was not there or just a poor representation (shocking, I know) of the real thing. The kits didn't come with an engine, just the lower half as a one piece add on to the undercarriage, not really up to today's standards but at least it sorta looks the part. From the photos I dug up on the web the kits look fairly accurate and scale out within 1 inch for wheelbase, width, and length.
I did add a few extras that made them a bit more unique so I sculpted a couple of mattresses to throw over the hood to fight off that Russian cold. I was having so much fun with the Green Stuff putty I also added worn seats which I thought was a vast improvement over what the kit provided; essentially just a plastic box.
Any comments or things I might correct always welcome.
Cheers,
Rick
