These arrived today. Thought I would share some pictures.
Overall I think they look fine. Standard heavy 40' flat with balsa wood top. The tanks are plastic and nothing moves. But I think they are okay
They come with 4 balsa wood blocks with double sided tape - I have not installed them.
The holes in the flat could take chain as they go all the way through.
Maybe some black paint on the frame behind the wheels. Again maybe this is correct - will again have to look through some books.
Overall I like them. Need to add some chains maybe - have to study that. The only thing I see wrong with the UP version is the built date on the flat 1951 oops. I am sure a few Sherman's were around then. But I was thinking WWII era. Personally these plastic tanks are pretty good. I have some metal ones I bought years ago but can't get to them to compare right now.
