Lance
I don't think the name is I. I. C. Kollmann but I.C. Kollmann. The first I is a double strike, not a big deal it happen often. First time for this distributor mark for me. Nice pick-up.
Is this picture below a picture of your bayonet. The reason is I don't like the way the grips fit on this one. Could be OK, would like to see in person.
