Hello,i can't be sure about this one,there really is to much glare on the pictures,what i will say though is that i like the chinstrap on this one much more than the luftwaffe one(that does'nt mean the luft one is no good!)it looks to be a thinner thickness of leather which i like to see on original straps.
Can't tell from glare
sorry bad decal at least
It looks like an original liner and shell, but I can't comment on the paint from these photos. The decal is bad.
Looking for WWII U.S. dog tags
Yep better pics would be good, but from these photos the decal look like a Q fake. Probably a original no decal m42 with a fake decal
