I posted here to see if anyone had a feel for the NIB part as well as any specifics to look for to see if it had been fired before.
To maintain its value you keep it new in the box and keep all components in the wrap. Keep the box out of sunlight so it does not fade. If you take down the pistol look at the rails for wear to the blue, scuff marks or lateral scratches in the chamber to see how much use it has. Is it greased or oiled? I bet it is rather dry as a NIB pistol that was sitting in a display case or drawer since the 1990s. Do you see dried oil. Do you see any signs of brass color on the barrel rifling? Do you see any evidence of powder blackening on or around the chamber or barrel. There should be very minor scratches or scuffs to the outside finish. I see none, no mars to the finish by the safety or the side clip. It looks like the pistol was never used or taken out of the box which is perfect for a collector of type specimens.
Shoot it and you got a run of the mill cheep dog. Collectors want it for its condition, it is a type specimen of an early 90s Norinco, and the box and its contents. It is like an in the arsenal wrap Enfield, Mas 36, or Mosin. Just much less value. Buy a shooter and preserve that one as is. Like vintage BB guns, you want them new in a box-- that is where the value is. I'd rather have a BB Tokarev, a Russian IZH MP 656K made from a real surplus pistol.
Norinco, I always considered those as cheep pistols. A vc bring back, a beat Chinese Tok commands much more respect and value. So look for brass color markings, black powder marks and wear to the hammer, wear on the receiver body at the side take down clip and scratches from sliding it back to dissemble the pistol, wear to the rails and inside the rifling of the barrel. Do you see dried oil? Do you see scratches to the side panels of the mag and wear from the mag spring and follower going up and down when cartridges were loaded?
