Picked up a very good cond yugo 59/66 for $299.00 at gander. Field stripped it and the bolt for a good cleaning. It's killing me I haven't shot it yet. I was pleasantly surprised to see how cheap 7.62x39 steel case is! This is my first weapon in this caliber. I will be shooting the bejesis out of this thing. What I know after research on it. It is apparently a 1968 production per serial number. Has the type one ported grenade launcher. It has the yellow colored night sights (phopsherous ?) It is heavy. It looks mean. Absolutely love it. Wish I was up on posting pics. Sorry lame. But happy member of the sks club. Thanks
