This is a Czech made reproduction German WWI helmet chinstrap with brass hardware. These chinstraps were used on the spike helmets and later used on the M16 and M17 steel helmets. The brass hardware on the chinstraps was soon replaced by steel hardware chinstraps for wide used on the M16 and M17 combat helmets. It is only $3.00 to ship these rivets to anywhere outside Europe and only $2.00 to ship this item within Europe.
