The Helmet is an M40 with rough color. The only stamp i can see is NS 64. The Adler Decal looks very strange to me, i think its a rare variant because the lines are with and not black. I thinkl the helmet must be original. It was buy for 70 € before 9 years. My problem is i can not post any pictures. Please email me at zbv500@aol.com.
