1) I think this is a set of Gaming Models T-26 tanks.
2) I think this is another T-26 but I am not sure. Is it a different make or is the difference between it and the Gaming Models ones that severe.
3) Next up is what I think is a KhT-26 flame thrower tank, well maybe.
4) Lastly is ... well, I have no idea. Almost looks like a KV-1 but its smaller than the others that I have.
Thanks for the help.
