This original early-WWII helmet is in exceptional condition. The McCord manufactured fixed loop helmet shell's considerably early heat stamp of 51B 1 dates the helmet's production to mid-1941 - months before the United States entered the war. While still a relatively low heat stamp, this stamping is likely the highest of the 1941-format, with the additional number suffix soon to be eliminated. It retains its original factory paint, cork texture, and khaki chinstraps. The chinstraps feature the early cast-brass buckle, carried over from the M1917A1 helmet. The helmet's early style fixed loops remain strong and intact. The Hawley manufactured helmet liner retains aluminum washers, a first pattern rayon suspension, and a rarely intact stationary leather liner strap, also dating the liner's production to mid-1941. The rayon suspension is strong and intact. It comes complete with its original size 3 rayon neckband and headband. This helmet set would be nearly impossible to upgrade.
