This is an original WWII Hood Rubber Co. manufactured low pressure helmet liner. 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 faintly ID'd khaki suspension is strong and intact. It comes complete with its original Joseph N. Eisendrath Co. manufactured double wire headband and Johnson & Johnson Co. manufactured neckband. The liner's exterior retains its original olive drab factory paint and Captain's insignia.
