Pitbull,
You're right on target! Could someone possibly merge the two threads somehow? That might be helpful for future reference, no? I have no skill for that, sorry... everything would be wiped out!
DC - What you have there is a nice example of, ein "Bayerischer Hirschfänger mit Löwenkopf und Kautschukgriff." Translated this means, "Bavarian hunting-sidearm with lion's-head and synthetic grip." Great detail to the face on these.
Contrary to most descriptions these grips are
not artificial horn,
not the real deal. Just look up the German word, "Kautschuk... " I'd say there are likely presentation-models with genuine horn-grips, if you don't mind burning little holes in your grip, you'd have to test with a red-hot pin to be sure. I'd say an original horn grip would be just a slight bonus, nothing to make a big fuss over.
As a quick aside ... I once had an unmarked WKC with Damascus blade that had little pickel-bumps running along the deer-leg crossguard motif. Never saw another like it.
A very handsome weapon by any standards.
Best!
Bill
