I need some help identifying two M1 helmets.
The first one is the one photographed with the plastic liner. It is smooth on the outside of the metal bit, and the helmet liner itself is green. There are no markings in the helmet liner I can find, but stamped under the front rim is LS 827
The second one is more interesting. I am not quite sure what material the lining is, but it has a leather chin strap and leather padding. A stamp near the crown reads US20. The steel helmet itself has no markings I have found, but on the chinstrap on the ball part that clips in is what appears to be a little anchor stamp. The outside of the helmet is matt and rough, almost like sandpaper. A bit of background on this one; I brought it nearly 15 years ago in a Thai market, at a stall where there was lots of other US militaria. It was in a US choc-chip helmet cover, but this was ill fitting and probably an addition from the seller.
Any help on IDing these helmets would be much appreciated.
