I came upon this bayonet and would like to know something about it. There are zero identifying marks on any of it. I'm thinking it's some cheap knock off because of lack of markings. I found a couple or three on line that were identical for the most part but they all had some numbers/letters. It belongs to a friend and he gave it to me to figure out what I should pay him for it. That is, if i want to buy it. No markings/cheap knock off and all. I'm pretty frugal/cheap, but when I get accessories for my guns I like mostly authentic. It does fit my Polish AK. I'm thinking @Boboclown is the AK aficionado around here. Not that there aren't other of course.
