Ahh you are speaking my language brother!
I've gotten rid of my US WW1 stuff but still have a complete Austro-Hungarian set from WW1.
At the moment I also have stacks of war-dated Brit Battle Dress that I'm trying to figure out what to do with. I'll try my best to get some pics up here. Sadly all of mine is packed away as mentioned earlier. Finding it is half the battle.
and another pic:
French M15(?) (rarer export model), Belgian WW2, Italian WW2, Danish WW2
Romianian (Dutch-made), Soviet, Slovak WW2, Bulgarian WW2-post war
German M1916, Austrian, WW1 French, WW1 US
