The germans didnt made any Vz.24 bayonets, they only ordered production in Waffenwerke Bruenn plants, by reworks it could be certainly done in camp, but there is no reason for stamping parts of the bayonets that are hidden as inner side of grips? When we assume the marking is a property marking of SS has no practical sense mark a hidden part with this marking. By DH on crossguard it must be certainly examined but without picture is nothing more to say. best regards,Andy
