I just sent a check out for a new helmet!
It is just a black shell, but the inside is stamped ET62 (Maker mark and my size) and 832 (lot number). The lot numbers' other brethren, lot number 830, 831 and 835 are all Single Decal Luftwaffe helmets. They were painted Feldgrau (Field Gray), and had a single Luftwaffe decal. After the war it was sent to Czechoslovakia to be used in the fire service, which is why it was painted black. It is in super condition, and I plan on repainting it back to WWII specs, adding a decal, liner and chinstrap, and restoring it back to what it used to be. I'll make a YouTube video about it as well. At the very end, I'll paint my last name on the inside of the rim like all WWII soldiers did. (I have a German last name, so it fits).
