The owner was a World War II veteran and brought this home. I’m not sure what the writing on the inner lid translates to. I’d be happy to try an answer any questions. German World War II original helmet with incredible detailed decal. The leather strap is in great condition. The leather lining has a B 56 stamped on interior. There’s an RL239/10 stamped into inner lid along with the German writing and the big 55. There’s a small dent on the right side near the back. This is an incredible piece of history. You’ll be hard pressed to find a better one. The item “WW2 GERMAN Helmet LUFTSCHUTZ SINGLE DECAL ORIGINAL UNTOUCHED CONDITION” is in sale since Sunday, August 12, 2018.
