hello everyone, a friend of mine is looking to get rid of some of his military collections and he's got this helmet. To me it looks to be refurbished but i know nothing about these helmets. i know they are different from the M40s and M35s. I just want some of your input. Is it real? Is it refurbished? Anything off about it? I know the liner is wayyyyy too nice to be old and the chinstrap does not look original. Unfortunately these are the only photos I will have of the helmet. I appreciate all of your comments and thanks again!!!
