I’m new to the world of steel helmets but I decided to do some research and then go out and find a period piece. I picked up this helmet yesterday and I believe it to be a period M42 single decal, although it is in somewhat rough shape I enjoy the rougher look. The decal appears to me to be correctly applied and shows wear consistent with the rest of the helmet. The remnants of the liner are still in the helmet and it also had a batch number of what I think says 3081 with a partial text above it that I can only make out a 6. This is located on the rear of the helmet.

I’d like more experienced opinions as to if this is an original piece and your thoughts on the helmet as a whole, thanks!
