Hey, on 192w theres w.k.c on opposite side as maker. Forget to post that pic but got it here.
Red bayonet one has absolutely zero marks/stamps on it outside (havent opened it). On holster theres J.sch 1940 and 4670 on other side.

Black one 192w/w.k.c on ricasso. 44.cul/3386 on holster.

Any more details you want?
