Point taken Teo, as noted the forms themselves do not have rigid geographic boundaries, but indeed the decorative motif and in degree certain nuances in the element designs can distinguish certain regions, as you have shown.
Thank you for the kind words on my example. These markings do seem German but do not match exactly with known examples of makers in the compendiums. It has been suggested many times that German shops may have been producing 'blanks' in blades which were then stamped with interpretations of these marks at entrepots receiving them.
I think the diffusion of this general hilt form has been a well traveled conundrum for a very long time, that will be some thread!
