"BNIB"... My bad, "brand new in box" but that's impossible since it's 30 odd years old. "ANIB" would be an accurate description. It's a square butt 10-5 with It looks like it was purchased and put in the safe. There is no turn ring and even almost no marks on the frame near the firing pin from opening and closing the cylinder. The finish is unmarked. It is not a highly polished finish, but it is unmarked... no pits, rust or blemishes that I noticed.
The stocks are checkered square butt walnut magnas but I don't know if they are marked with the serial number. I didn't remove them to check (but it would be a safe bet that they are original to the gun). The box, wrapping paper, literature and an unopened "cleaning kit" is included and the label on the box matches the gun in every way. Truly, it is a "ANIB" gun.
