You have a Russian SKS, made at the Tula factory.
The three most common, are the Chinese, Yogo's and Russian. Once you handle one they are pretty easy to identify. As mentioned; you have a star which is Russian. In addition to the star, you might even see a manufactured date. I can usually spot the difference from a distance by the furniture, bayonet type and grenade launcher. The Russians are more desireable than the Chinese. ....
