Beautiful saber! The knot on your saber as already stated is for a Heer NCO bayonet but I have seen them on Heer swords also. Wither this was allowed or not I do not know. The knot on yours may have been there since the war as I have seen all kinds of knots on all kinds of swords and daggers. I believe the GI?s stuck whatever knot they could find on them just because it looked good. It?s going to be tough and expensive finding a Justice Official knot, good luck!
