This is an original mid-WWII Seaman Paper Co. manufactured M1 helmet liner. The exterior retains its original olive drab factory paint finish. The front of the liner showcases Staff Sergeant's stripes, while the interior is named to a Cox. It features green-painted steel A-washers, dating the liner's production from mid-1943 to mid-1944. The original khaki suspension is strong and intact. This helmet liner would display quite nicely with the addition of mid-war accessories.
