This is a steel buckle reproductions of a German WWII helmet chinstraps that is marked with an RBNr number "R.B.Nr 0/0390/0204". RBnr numbers first appeared in 1942 so the buckle is a steel one as it should be. On top of that it has been artificially aged to give it that lived in look. It is only $2.00 to ship this chinstrap anywhere in the US, Canada, Aus. NZ. and most of Asia and $1.00 within the EU. Trust me you will like this chinstrap or I will give you your money back!
