An excellent example of a genuine complete Vietnam War era U.S. M1 helmet. The U.S. M1 helmet was made by McCord in the 1950's and was reissued in the 1960's and has a heat stamp number: M 312 A, retains its original apple green paint from when these helmets were reissued, front and both sides have remnants of divisional/rank markings in white, chinstrap has anchor markings to the metalwork, bale clips are rare with bullseye stamp marks only seen on early 60's U.S. helmets, chin strap metalwork has remnants of green paint, another sign of early issue. The genuine U.S. P64 liner is in excellent shape and was made by Marmac, ink DSA (Defense Supply Agency) contract markings to the suspension webbing and was made in 1964. The genuine U.S. headband/sweatband is also DSA ink contract marked and is dated 1969, headband is named to a soldier along with their service number: Carroll Proctor 212-42-2389. The genuine U.S. nape contract marks are faded and was made in the 1960's. The genuine U.S. Mitchell cover retains its colours and is contract marked 9005 indicating it was made in 1965, around the outside of the cover is a genuine U.S. post-Vietnam War elastic helmet band with ink markings to the front. A very nice complete M1 helmet.
