Hi John,
Here are better images of the von Schellenberg Katzbalger at the KHM Vienna. Thought I had posted them somewhere here before but can't find them.
The close-ups of the hilt in color at the bottom are mine. Even if you are lucky and get special permission like I did, and are allowed to use flashlight, taking good pictures is extremely critical in the Vienna exhibition (as in most museums when it comes down to guns ...

).
The blade mark on the ricasso is an Italian-style crowned Greek pi.
Enjoy,
Michael
