I had one back in the mid 90's, at least thats what the seller told me the variant was called.
It was NORINCO manufactured and used AK magazines (just like the SKS-D) and a shorter barrel. Don't recall what the barrel length was but it was non-restricted at the time I purchased it. Purchased from Wolverine at a local gun show. It also had a crudely made (standard ChiCom fit and finish) light colored monte carlo stock (raised cheek piece) and bayonet (and lug) was absent.
Sold it just prior to C-68, wish I had kept it. Especially seeing the prices that a SKS-D commands these days.
Its the only one I ever saw, good luck in your search.
