That *is* unusual. Those curly secondary quillons are--at least in this configuration--unique in my experience. I wonder if they were some sort of pas d'ane supporting a bell guard that has been lost over the years? That'd make some sense if it's dated to 1640, but I've never seen a smallsword where the quillons and pas d'ane are separated like that.
