Scroll down this page to: "USAAF Rough Wear Type B-5, Contract 17756" - a typical fighter pilot helmet for P-47, P-51 pilots for high altitude and cold weather... Also on this page are "USAAF Type B-2, Eastman" and "USAAF Rough Wear Type B-2, Contract 17756" hats which were worn mostly by enlisted-only crewmen on bombers, but some fighter pilots also wore them...
