This is an original late-WWII Firestone manufactured M1 helmet liner. The exterior's original olive drab factory paint is rust-stained. It features blackened brass A-washers, dating the liner's production from mid-1944 to 1945. The Lapeer Fabricators Inc. manufactured khaki suspension is strong and intact. It comes complete with an original 1945-dated neckband - also manufactured by L.F.I. This helmet liner would display quite nicely when completed with additional accessories.
