An excellent example of a genuine complete Vietnam War era U.S. M1 helmet. The U.S. M1 helmet was made by RJ Stamping and has a heat stamp number: 603, helmet appears unissued and still retains remnants of the packing tape inside the helmet. The genuine U.S. chinstrap has anchor markings to the metalwork, and like the helmet also appears unused. The genuine U.S. P64 liner is in excellent shape and was made by Marmac/Firestone, ink DSA (Defense Supply Agency) contract markings to the suspension webbing and was made in 1972, like the helmet it also appears unissued. The genuine U.S. headband/sweatband is also DSA ink contract marked and is dated 1971, and comes with a genuine U.S. nape strap with DSA ink markings and is dated 1969. The genuine U.S. Mitchell cover retains its colours and is DSA contract marked and made in 1970, around the outside of the cover is a genuine U.S. Vietnam War era elastic helmet band with double box stitching. A very nice complete M1 helmet in excellent overall condition.
