No clue, it was only being sold as "Chinese SKS". I only noticed the markings by chance. Other than that it is all matching and all the metal except these tiny micro pits here is almost perfect. I would still be satisfied with it anyways. The guy actually did a nice deep cleaning on it before he sold it too. Fellow is a Garand/M1icon Carbine/SKS seller that frequently has tables at this show.

Only downside is the stock has been sanded, but that is life.
