Welcome to the group!
Guessing the bayo lug "ears" have been ground or filed off. The "1" in front of the "56S-1" ( which normally would have an under folder stock) indicates a rifle that was caught in port as the AT and unconstitutional F tried to figure out the meaning of "Sporting Purpose" as ordered by George Bush the First. It was marked with the extra "1" because it seemed that Bush1 thought that the name as well as other featured made the rifle evil and therefore non-sporting. Changing the name, removing the bayo lug or just the ears, at first tack welding a cover over the threads of the barrel muzzle and replacing the underfolding stock or fixed stock and pistol grip with that famous Bush-hole stock made the rifle angelic, incapable of being used for evil purposes... sick, stupid.
Depending on what was done to that rifle, some collectors would like it due to the timing of importation and angelic conversion. Does it still have the under folder? Some had the folder placed in the folded position with the Bush-hole stock installed over it. Some had the folder removed with plates riveted over the folder holes.
Later marked as NHM90 or MAK-90, what you paid is the current going price for the post-Bush1-ban rifles.
