This is a set of 3 reproduction German army WW1 steel helmet rivets. These rivets work for the German WW1 steel helmets, M16, M17, M18 and the later model Austrian helmets. The set comes with 2 thin head rivets and one thick head rivets. The thin head rivets go in the front so it does not interfere when the front armor plate is set on the helmet. Do note that the WW1 helmet rivets did not use the washers with the rivets like the WW2 rivets. It is only $2.00 to ship these rivets to anywhere outside Europe and only $1.00 to ship this item within Europe.
