About Winchester Model 12

Oliver F. Winchester founded Winchester Rifles and Shotguns on February 20, 1866. Their first rifle was the Model 1866 lever-action rifle .44 caliber rimfire, following earlier rifles like the Rocket Ball, Volition Repeater, Jennings Rifle, Smith and Wesson pistol, and Volcanic Repeating Arms.

It was available in 12, 16, 20, and 28 gauge and in various grades, including Field, Fancy, Skeet, Trap, Pigeon, Tournament, Featherweight, Heavy Duck Gun, Riot Gun, and Trench Gun.

The design was improved by B. Henry Tyler, which made the .44 caliber metallic rimfire cartridge powerful enough to compete with single-shot rifles of the time. This established the Winchester Repeating Arms Company as one of the world’s leading firearms manufacturers, and the rifles produced by them are highly valued by collectors today.

The Model 1912, also known as the Model 12, was Winchester’s first slide-action hammerless shotgun designed by T.C. Johnson. It had a strong frame and a hidden hammer, and the chamber was lengthened to accommodate 2-3/4 inch shells in 1927 and later for 3-inch shells.

The Heavy Duck Gun was introduced in 1935 and was chambered for the 3” magnum 12 gauge only. During this era, all Model 12s had Nickel Steel barrels, except for the ones with Stainless Steel barrels.

These 3” magnums were also offered as Trap guns and Pigeon Grade guns, and special features may include barrels with solid rib or ventilated rib, fancy stocks, checkering, carving, and engraving.

The pre-64 Model 12 Winchester was designed in 1912, with production from 1914 to 1963, during which over 1.9 million guns were sold, with milestone serial numbers set aside for presentation to notable individuals. Production continued until serial number 2,027,500 in 1980, but this appraisal course only provides values for pre-64 Model 12 Winchester shotguns.
