Hi friends I am very sorry that my question on fallschirmjager helmet had raised hot discussion between members ............ I hope that sometimes is better to received an unwanted answer that to deceive ourself! Now I am sure that my only original helmet I'll be probably my first that I found when I was 14 years old in an ancient palace of my aunt............... My helmet isn't Czech, I have seen theirs some years ago but they are generally large size (58 or 60) and more light than mine. In any case I would be grateful to some members that should be able to send a pic of original one. Sorry for my poor english, but as Xavier I have some problem to translate Italian in English language OTIS
