WTT: AK47 Bayonet for your Mosin Nagant M28 Bayonet. My 1938 Finnish M28 Mosin has a specific Bayonet attachment. Thanks. Hello friends, It's probably obvious where this came from to some of you, but I do not know. Steel scabbard, the number 4493 is on the butt end of the bayonet. It appears to be a bakelite type handle. The barrel mounting holes are 5/8" to11/16" in diameter. 1. Can someone tell me what it is from? 2. If it is similar value, I'd like to trade for a solid M28 bayonet from a Finnish Mosin Nagant.
