This is an original early-WWII U.S. low pressure St. Clair manufactured M1 helmet liner. It features a rare green painted interior, steel rectangular washers, remnants of a stationary leather liner strap, and a first pattern rayon suspension. These characteristics date the liner's production from April to May 1942; these two months were the only time in which liners with green painted interiors were being produced, making this an exceptionally rare item. It comes complete with an original rayon headband and neckband. The liner's exterior exhibits its original flat olive drab factory finish and silver painted ID code.
