This Stevens manufactured early variation pistol grip hard wood stock sub-assembly with butt plate and straight slot butt plate screws is for the earlier model 59 bolt action shotgun without the side safety and attaches to the front dovetail block using the early variation takedown screw (both sold separately). This stock sub-assembly is in very good condition containing light dings, handling marks and has been nicely refinished by a previous owner.  (file photos)
