The Postal dagger being a later production run edged weapon in the much smaller numbers produced than the SS, has always been the scarcer dagger to find.
Had the Germans given it a NSKK/SS type chain on it IMO it would have truly an stunning looking piece. The quality and design of the daggers "Art Deco" look is very apparent in this model.
Clearly a "must have" in any dagger collection.
