I just traded for a 90% plus condition chinese SKS. It has all matching serial numbers everywhere. It also has a chrome lined or stainless lined barrel. When running a rod through it, there was no trash, only a cosmoline substance (like new). Has boyonet, storage hole witch had cleaning kit, and the cleaning rod under bayonet. Also has sling with chinese markings. I will say that I am in it for less than $250... Is it of any value and did I get a good deal? Is there any way to determine year from serial number? I just found out after research that it is a bit of a rare model. It has a "26" stamped inside of a triangle, smooth stamping, made in 1956 for Cinese Police. It even has matching sling with it.
