Hello all,
I discovered an interesting find (at least to me): when looking at the book entitled 'The Landsknechts' (Mens-at-arms series number 58, Douglas Miller and GA Embleton), I noticed that, facing the third quarter of coat-of-arms depicting the 'three moons' motif (which is found on katzbalger's blade), the fourth quarter of the same coat-of-arms shows the personal flag/standard of Georg Von Frundsberg (Lord of Midelheim), the father and supreme commander of Landsknechts !
Therefore, it appears clear that this particular 'three moons' motif should be somehow 'linked' to the Landsknechts...

To Michael: for information, the etching ('Passau wolf' and 'three orbs and crosses' motifs) on katzbalger's blade is not light (the pics of poor quality do not actually render justice to etching).
