Winchester Model 12 Heavy Duck 12ga - 30" Full Choke - 1939 - 806299

"The Perfect Repeater" in a Pre-War Heavy Waterfowl Configuration

Designed by legendary firearms engineer Thomas Crossley Johnson, the Winchester Model 12 (originally Model 1912) set the gold standard for pump-action shotguns throughout the 20th century. Celebrated for its smooth action, machined steel internal forging, internal hammer, and takedown receiver design, over two million Model 12s were manufactured, earning it the enduring title of "The Perfect Repeater."

Carrying serial number 806299, this pre-WWII example was manufactured in 1939. Chambered with a factory 3-inch Magnum chamber paired with a long 30-inch plain (no rib) barrel choked Full, this specific configuration represents Winchester's famous "Heavy Duck" setup. Built to throw dense patterns of heavy shot over long distances, pre-war Model 12s with 3-inch chambers remain highly regarded by classic waterfowl enthusiasts and Winchester collectors.

Condition and Action Highlights

Overall Status: Rated in good condition overall, presenting as an honest, pre-war working shotgun with significant natural finish patina while retaining complete mechanical excellence.

Patina & Metal Finish: The original factory blued finish is heavily worn away across the chamber end of the barrel. The bare steel has aged to a smooth, uniform gray patina, completely free of active rust or corrosion. Bluing still remains on most of the receiver, magazine tube, and forward half of the barrel. 

Walnut Stock & Forend: The original American walnut buttstock and ribbed forend are in good condition. The wood displays handling marks, light finish wear, and minor storage dings, but is structurally sound with no cracks, chips, or severe gouges.

Recoil Pad Condition: The fitted rubber recoil pad is badly deteriorated, showing hardening, crumbling, and dry rot from age (would benefit from a period-correct replacement).

Action & Mechanical Performance: Mechanically excellent. The iconic Model 12 slide action cycles with smooth, precise lockup. The takedown mechanism functions correctly, and the trigger releases crisp and tight.

Bore & Barrel: The 30-inch plain barrel features a clean, bright bore free of ring bulges or severe scoring. The barrel is marked as a Full choke but has not been gauged.
