Your SKSS is the first I've seen with the bayo mount neutered. I'm not saying that more weren't made that way, just that it's the first I've seen that way. Since it was only made the one year, I'm not sure if it was neutered stateside or factory. A quick pic of my SKSS:
Mine is currently fitted with a Chinese 20rd fixed magazine, but it wasn't produced with that mag. I have the original non-serial
numbered 10rd fixed mag that goes with it.
The Chinese SKS Guide
says they came with matching serial numbered parts. But all that I've seen, (including mine), came with only the receiver, bolt carrier, bolt, and stock having stamped serial numbers. The magazine, trigger group, and receiver cover are non-numbered. Examples:
already pointed out, if you could find a stock and handguard set in the pinned barrel configuration, along with a 10rd fixed OEM magazine, you would be most of the way to returning it to it's original glory. Without the original serial numbered stock it will not be as collectable as it once was. But it will hold it's value as a "para-length" carbine.
a very short little carbine with the folding stock on it.
I have one of the Combat Exchange folding stocks for this one too. It does make a compact little house gun. And the 20rd mag compliments the package.
Just a quick suggestion; Check your gas tube and gas pistion for any carbon buildup, especially look for any rust or corrosion. Keep it clean! You won't find extra parts for these, they are a rare length on both parts and hard to find. Just a suggestion...
