This is an original WWII leather liner strap. The leather has dried and the hardware is rusty. The curved buckle is green painted steel, dating the strap's production from mid-1943 to mid-1944. It features non-marked green painted steel rivets. The underside of the leather is stamped with an 'H', denoting production by the Hagerstown Leather Co. This would be an ideal strap for a high-pressure helmet liner with green painted steel A-washers.
