The chinstrap consists of a long end which measures 36-40 cm and a short end that is approximately 5 cm. The long end has 13 circular or oval shaped holes for the buckle prong. The short end has a metal buckle where
the chinstrap can be adjusted. Both ends are secured to the bales (D-rings) on each side of the liner with retaining studs.
The tip of the long end is normally stamped with the manufacturer’s name, location
and year of production. These markings are often illegible due to wear and/or faint stampings. It was also common for soldiers to shorten the long end by cutting off the tip.
There are several variations in color,
thickness, materials and buckle design. With some exceptions, the Luftwaffe used brown colored leather while the other military branches used black. However by 1940 all branches utilized straps of both colors. Early chinstraps were manufactured with aluminum
buckles and retaining studs. As the war progressed, chinstraps were fitted with painted or unpainted brushed steel buckles.
