Saw this piece on Ebay and thought it was interesting. It is a late Russian AKM T2/AK74 bayonet with modified pommel. Though relatively scarce, I found this example unusual in that it seems to be a Bulgarian rework. The grip appears to have had the original serial number removed, and new one etched above. The scabbard has neither the Izhevsk triangle nor Tula star, so suspect it must be Bulgarian. Reinforcing this is the serial number on the bayonet "AB 3487". There was only one photo of the obverse of the scabbard. I was not able to discern the entire serial number, but did see it was a 4-digit, "AB" prefix serial. In looking thru AK47 The Grim Reaper 2, I saw a photo of a "29" date, Bulgy AK74 with laminated wooden furniture. It bears serial number "AB 3770". To my knowledge the Russians only applied a serial number to their AKM T1/T2 bayonets. Since the Bulgarians initially received Russian components to build their AK74s, they likely got bayonets as well.
