No worry about it, maybe they used in late 30 .ies chrome plating, i believe its no fake, only the finish of the bayonet could be replaced after WW2, the scabbard and frog are ok, the rough tooling on ricasso is normal same like in fullers for WW1 war production, i dont like only the spine blade area near crossguard,very heavy tooled for OEWG, but it could happened by preparing of the surface for plating.Nice piece offcourse.best regards,Andy
