I took the dagger down. I can not make out any tang markings. Just some light "dings" about 1-2mm wide and pretty much round. Lower crossguard marked with a round dent about 1mm deep and 1-2mm wide, no other internal marks. It is group marked "Wm" externally, as is proper. The upper guard is marked with a large "H" and what appears to be a "U" or maybe "O" in a circle on the other side of the tang hole (mark is smaller than the stamped "H"). Wood grip is stamped "WKS", and I have seen that before, most recently on a type 1 chained SS I used to own. I will be posting pictures shortly.
