This is really rare Austro-Hungarian ersatz, probably produced by Germans. It is listed in Vial but in standard version with usual scabbard. I bought it aware that I risk buying a fake. But now I think I rather made a good deal – it seems to be original, and the scabbard is unique, made of two steel sheets, old and corroded inside. And it is a NCO version…. Would be grateful if someone knows something or had seen this bayonet.
