What’s Included
- Unmarked external-hammer side-by-side 12 gauge shotgun
This side-by-side uses an underlever opening system paired with double triggers and exposed hammers, reflecting typical 19th-century design. It employs an extractor-only (non-ejector) system, with no top-tang safety observed. Capacity is two shots.
The 32 in barrels feature a narrow, plain raised rib. The overall configuration and mechanism are consistent with black-powder-era manufacture. It is possibly configured for black powder 12 gauge; verification by a gunsmith is recommended.
Furniture includes a straight-hand (English-style) walnut stock with a checkered wrist, a splinter forend, and a metal buttplate. Length of pull measures 14.5 in, and the platform is full-size.
No maker’s marks or proofs are visible, and the gun is unmarked for manufacturer, which is common on some period pieces. Its external-hammer, underlever architecture and extractor-only layout make it a representative example of the era.
