Helmets good IMHO. Gotta remember there was a fiberglass helmet liner that went inside these, so theres got to be room for that AND the head, and the suspension system that the head fits into. Too many M1 helmets we see on figs are much too form fitting and shallow. The M1 helmet came in one size, with the helmet liner providing the sizing. That being the case, you can have a pretty broad spectrum of large and small heads, all using the same size helmet shell. One of the first things I look at on US figs is how well the steel pot is replicated, I think this one is pretty good.
Love the stance. Just a little movement, and a lot of tension in preparation for action.
