Awesome help, guys. I had been looking under Russian or Chinese equipment and could not find anything.
I should have guessed British with their past history in Iraq. In a warehouse on this base, I found a bunch of British WWII paratrooper helmets with a different liner installed. Look like they did the same thing with this cannon, installed a differernt shield on it.
I would have never guess Czech on the AA gun, but I do remember some cyrillic looking writing on it.
Thanks again and now I just have to find some kits to build these. And a fat soldier to model myself.
