An amazing restoration has been done on this helmet. Some concrete was applied to the exterior as some originals. A paint on it will make it perfect as you wish. Some originals were also found with raw concrete on it. The inside has not been modified so you can appreciate wearing an original. Original parts are : - M42 Shell with markings - Original aluminium Liner dated 1943 and rare manufacturer Litzmannstadt (Łódź ghetto). - Original rivets Reproduction and post war : - Leather for the liner- Chinstrap, high quality reproduction with Rbnr number on it. - Goggles that are post war identical to ww2 ones. A great helmet, museum quality, it has already some real rust on it !
