Hello,
Here are some information from specialized books, that I got on the web (Rudolf Cronau's Geschichte der Solinger Klingenindustrie, published in 1885; Gyngell's Armourers marks, page 30).
- The shape of 'orb and cross' motif found on katzbalger's blade is exactly the same as the one shown on pic (plate 1: number 24, and plate 2: middle orb mark), indicating a 16th century period, coherent with what is expected for a 16th century katzbalger's blade;
- The 'three orbs and crosses' motif -with orbs and crosses arranged in a triangle- is also reported to be typical German 16th century (not shown in this post: I have to refind it on the web

), also coherent with what is expected for a 16th century katzbalger's blade;
- The 'Passau running wolf' motif etched on both sides of katzbalger's blade is exactly the same as the one described to be mid-16th century, also coherent with what is expected for a 16th century katzbalger's blade. Interestingly, it has some additional details that were also reported amongst known variants of the 'Passau running wolf' (see plate 3, number 14).
Such blade marks are therefore totally coherent with a German 16th century blade...
