This is an original WWII Hood Rubber Co. manufactured low pressure helmet liner. The exterior's wartime field repaint has worn thin, exposing the liner's intricate design. The A-washers are non-painted steel, dating the liner's production from late-1942 to early-1943. The interior crown features the iconic disk pattern and silver painted HR. The khaki suspension has frayed in some areas, but remains intact. It comes complete with its original early-WWII headband, neckband, and a recently installed green-buckled leather liner strap.
