First SKS, just want some info!

I just bought this SKS! I'm very excited about it. It's got a bayonet! Crazy. Anyway, there are all the markings on it. Is this a good find? I think I've heard the Yugoslavian's sure knew how to machine a firearm. It has 204703 stamped on it in a few places. Any and all information is appreciated! Thanks! Also, shout out to the guy at the gun show who sold this to me and gave me two free stripper clips and a sling! (Ignore the salsa and the .22lr magazines, they're unrelated.)
