Hoping someone here will know more about this than I do. I’ve never seen a serial number like this on a bayonet. I apologize in advance for the picture rotation being screwy. That’s the way it was going for me today. I had two lines of thought as to why this may be. The first being that somebody has Force matched this blade and just started stamping serial numbers on it themselves. The second being that this was reissued down the road. The Scabbard is marked WK C 1939. It looks like any original Makers Mark on the blade was removed and the blade was perhaps reblued. I could probably see the original numbers on the blade with a little acid but I didn’t want to do that. Any thoughts are greatly appreciated
