yes star on top is Tula in russia. there are a number of different makes but the most common are russian tula, Chinese factory 26(a triangle with 26 inside) and yugoslavian which is the only SKS to have a muzzle break. less commons I'm aware of are north vietnamese that have a star on the side of the reciever and are extremely rare as the factory was an early target for US forces and albanians that have a longer than standard handguard.
that's about the extent of my SKS where-dat-come-from knowledge.
