What’s Included
- Winchester Model 37 Steelbilt 16 Gauge single-shot shotgun
The 28 inch barrel is plain (non-ribbed) and fitted with a fixed Full (F) choke, suited to tighter patterns. Chambering is 2 3/4 inches, and capacity is 1 round. The action is a single-shot, break-action design operated by a top lever.
Controls and handling reflect classic Model 37 features, including the curved "pigtail" style top lever and a single barrel with extractor/ejector for positive case removal. Length of pull measures 13.5 inches. The wood pistol-grip stock pairs with a long splinter forend for a traditional feel.
Markings are clear and correct for the Steelbilt series. The barrel rollmark reads: "WINCHESTER TRADE MARK - MADE IN U.S.A. - MODEL 37 - STEELBILT - 16 GA - CHOKE - 2 3/4 CHAM." Winchester oval WP proof marks appear on the barrel and receiver. A checkered steel buttplate marked "WINCHESTER" completes the configuration.
Built in the United States, this Steelbilt example aligns with Model 37 production norms. These shotguns were not serial-numbered, and this one reflects that period-correct trait, along with the fixed Full choke and straightforward break-action operation that define the model.
