By Erfurt Arsenal. The “Kurzes Seitengewehr” or “KS” bayonet. “KS” marking to crossguards indicate use by the “Kolonial Schutztruppen”. Wooden grips with screw bolts. There are six ribbed lines to grips which are questionable as the standard model does not feature these. Ricasso also carries the Crown cypher of Kaiser Wilhelm 11 who reigned from 1888 to 1918. Good overall.
