Well spoted Killy...

Yes from all accounts it is a rather treasured patch. Back in the day, if a German sniper was caught with this item it was a death sentance. The soldiers were ment to attach 'em onto there clothing or battle tunic, but most would place them into there pay books, if kept at all.
Being from German stock I was call Kopfjagger from my platoon Sgt whilst on my snipers cse in the Infantry. Not having a clue as to what he was talking about, I went looking on the net and bookstores.
I named a longbow with that name, and it lived up to it more often than not.
