I usually live on the edged weapons forum, but haven't got an answer yet. I tried the firearms section, thinking it might be a holster adapter. No luck.
I have never seen this belt adapter on a bayonet scabbard before and I don't think is belongs there. (of course it would make sense if a GI would want it on a regular belt).
Does anyone know what this belt adapter was used on? It is totally unmarked. Thanks.
