What’s Included
- Winchester Model 37 Steelbilt .410 Bore single-shot shotgun
The Steelbilt designation denotes a strengthened steel receiver, adding durability without excess weight. This feature, coupled with Winchester’s “WP” oval proof mark, underscores the shotgun’s factory-original integrity.
.410 Bore Model 37 examples are notably less common than their 12 and 20 gauge counterparts, enhancing the desirability of this piece among collectors seeking gauge variety within the Model 37 series.
The 26" carbon-steel barrel is factory fitted with a fixed Full choke, providing tight patterns for small-game and varmint use. It accepts 3" shells, expanding ammunition options beyond many period .410s limited to 2 ½" loads.
Original walnut furniture features a straight grip and semi-beavertail fore-end for comfortable, controlled handling. The blued finish on both barrel and receiver retains strong coverage, complementing the warm walnut stock.
An external hammer, break-action design, and automatic ejector keep operation simple and reliable, while the front brass bead offers a clear sight picture without adding bulk.
