In first I must say that I create that thread and the pictures from a friend of mine (is on this site) who cannot use internet right now, i'm not a militaria collectioner myself so that will be hard for me to answer to your questions (if questions are posed) so here we go I just make a copy paste of what he let to me for make that subject.
I have this leather tank helmet and I want to have your own opinion on this one, I was always curious about that chinstrap that I never seen on soviet production (but we told me that could be an early model), the quality of the leather is really good for being a copy but we never know ... inside we can see clearly it was hard used the blue color is almost unseen other point about that if I returned the coating we can see the typical blue of Soviet tankmen, I've take for compared another of my helmet dated 1939 with blue coating (this helmet I have absolutely no doubt about him) and for finish I looked an old thread on Warrelics where I can see a pictures of a fake leather helmet with pictures of the snap, unfortunately they seem to look just like what I have on my own model.
For my part the quality of that helmet on the material used make me hard to believe that's just a copy but If I create this thread it's because I have a doubt about that (more about the snap) so ...
Fire at will gentlemen don't hesistate to give your opinion ! (with argumentation at least)
I'm not sure if I doing the right thing for the photos (the way i posted) he explain me how to make just hope I didn't make any mistake.
