This is an M1A1 LL Helmet - the LL stands for, Luftlandtruppe (air land troops airborne) used by the West German Paratroopers Post World War II. The Helmet is complete in very good condition. The Guy selling it sells WWII German Helmets and according to him it did not fit well with his other Helmets. I bought it for a very good price - $100.
