I have a garage sale find SKS rifle. Bought it for $250.00, still in the cosmaline. Grooved barrel. Very little damage to the wood but no extras (no sling, bayonet, cleaning kit, etc. Just the basic rifle.) Very minor scratches to the metal parts. All numbers match (01320). serial number: 71-01320. Can anyone tell me about it? How old it is or where it might have been made? The factory triangle is a 3. There are no Chinese symbols behind the 3 before the serial number. I want to give it my husband for Christmas but hate to gift him with something I don't know much about. He's been looking for this gun and an M1 for some time and I think I got a deal, but? Grandma would prefer not to be embarrassed by having bought a pig in a poke.
