This is an original WWII leather liner strap. The leather is unfortunately twisted and dried, thus we do not recommend trying to fit this strap over a helmet's brim, but rather it should be displayed just resting on the liner's suspension. 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. This would be an ideal strap for a high-pressure helmet liner with green painted steel A-washers.
