US paratrooper helmets as worn by members of the 11th, 17th, 82nd, and 101st Airborne Divisions during World War II. ATF creates these by converting US military steel pots & postwar Belgian liners. Externally, they look identical to WWII jump helmets. Comes completely assembled and ready to wear. (You may have to adjust the sweatband to fit your head.)What's the difference between these and the "Reproduction" helmets? The Belgian liners look almost exactly like WWII originals- and they are fitted with high quality ATF reproduction parts rather than the Chinese ones.
