I have not tried an M1icon. Next time I have it out maybe I will. It almost looks like it was chromed but isn't quite shiny/polished enough, possible dress bayonet but the scabbard obviously is not. Covered with grease when I got it. More important to me is finding my 1918 and direct comparing the two. They say the blade is slightly heavier on these also but until I find the other, I have no way of knowing. The small triangle is supposed to be unique to this variation.
