German, Austrian, I'm not thinking Dutch for these curved feldegen type that differentiate from the hilts with shell guards. I recently adopted a large haudegen with similar guard branches but a much simpler thumb ring. The straight walloon/haudegen cavalry swords almost uniform and there is that Austrian castle wall showing a dozen or so of these hilts.
In seeking out information regarding screws or not. Time period and area not necessarily a key but more so in pommel types and blades affixed.
All my pictures need sizing

lets see here. A handful resized for now.
A long thread and my Wundes blade sword with full size Fagan images on page three at the end. I'll work on those.
