This is an original WWII leather liner strap. The Hagerstown Leather Co. produced leather is quite soft and supple. The green painted steel buckle is the early variety with the flat lip, dating the strap's production from late-1942 to mid-1943. It features United Carr steel rivets. This would be an ideal strap for a helmet liner with either green painted steel or non-painted steel A-washers (including Hawleys and St. Clairs).
