Sorry.. There was only one state factory in former USSR were SKS was produced from very first day in 1949 to last in 1958 . Close to 2 million rifles where produced and some of them still in a service mostly in a support forces . After 1956 all production lines were given as a present to China and soviet engineers spent a few years there helping to provide quality and quantity... That is why chinese SKS's are not so bad...
