This is an original WWII United States Coast Guard Shore Party M1 helmet set. It is one of four USCG helmets the previous owner recovered in the 1960's from a Quonset hut at the grounds of the former Adak Army and Naval Airbase in Adak, Alaska on the Aleutian Islands. Helmets belonging to Naval and Coast Guard units were often marked at their sides with yellow discs in order to differentiate themselves from Army and Marine units during amphibious invasions. The McCord manufactured front seam fixed loop helmet shell has a heat stamp of 210A, dating its production to July 1942. In addition to its USCG markings, the helmet retains its original factory paint, cork texture, and brass-buckled khaki chinstraps. The Capac manufactured liner's original olive drab factory paint finish is good condition, with rust stains matching that of the steel shell's interior, indicating their long history together as a set. It features blackened brass A-washers and a khaki suspension, which dates the liner's production from mid-1944 to 1945. The khaki suspension is strong and intact. It comes complete with its original headband and black-buckled leather liner strap. The leather components have dried somewhat with time.
