What’s Included
- Winchester Model 12 16 Gauge pump-action shotgun as described
Manufactured in 1936, this Model 12 reflects the period’s nickel steel barrel construction and Winchester’s takedown system. Right-side ejection and the internal-hammer action contribute to the platform’s straightforward operation.
The 26 inch barrel retains a cylinder bore for wide patterns, with a 2 3/4 in chamber suited to standard 16 gauge loads. A ventilated rib with post supports and a single front brass bead (no mid-bead) provide a clean sighting picture.
The barrel is roll-marked "NICKEL STEEL - WINCHESTER - MODEL 12 - 16 GA. 2 3/4 CYL." confirming the chambering and choke. The tubular under-barrel magazine provides a 2+1 capacity.
Custom furniture includes a walnut thumbhole buttstock with a rollover cheekpiece and a rubber recoil pad backed by white/black line spacers. A smooth beavertail-style forend complements the stock, and the length of pull measures 14.0 inches.
The receiver is blued steel, matching the blued finish on the barrel. The gun’s U.S. manufacture and takedown construction round out a configuration that blends period-correct materials with practical custom stock work.
