I bought an SKS back in the late '80's that has no factory markings of any kind. No star, to triangle w/number. Only serial numbers. All but 1 number is the same but the one exception has "89" preceding the number found elsewhere. Serial number is in the #00800's but the one that differs reads 8900800. I know it's a CAI import and made in China. Any idea what this gun is (year of production, etc)?
