Welcome to the forum, and to the Commercial Chinese section Armyrn33
That's a gorgeous rifle you've got there. I would say, given the past 6 months or so of Gunbroker sales, that your rifle would be worth between $750 and $1100. Most of them that we see for sale are in excellent shape. Ones without boxes have been selling in the $750-$900 range. The original box and accessories usually adds $100-$200 onto that price. But of course, we all know it just comes down to how many people want your particular gun at the time
Does your rifle have the stripper clip groove in the bolt? Most of the early Beta Arms versions did. The ones I have on file with serials before, and after yours, all have stripper clip grooves.
Let's all also try to stop the bad habit of calling this rifle an SKS-D. That is in improper term. The proper model for this rifle is the
SKS-30. The SKS-D is what Midwest Ordnance called their in house made version of the SKS-30.
As for your other SKS, it looks like a Navy Arms standard paratrooper. However, in the one pic, I think I see the end of a scope mount. Can you get a better pic of that?
