This is an original WWI U.S. manufactured M1917 helmet that was converted to an M1917A1 by the U.S. government during a reconditioning process that first began in 1936, prior to McCord's new production line of 1941 manufactured M1917A1 helmets. The helmet features original olive drab paint and textured finish. The helmet's interior brim stampings are hidden beneath the paint, however its domed rivet heads denote U.S. WWI production. It retains its original leather liner and khaki chinstrap. The chinstrap exhibits the early cast brass buckle and box stitching, while the liner retains its original leather drawstring and crown pad. The M1917A1 was seen atop the heads of Marines fighting on Wake Island, Bataan, and even during the early days of Guadalcanal.
