Built during the 1914–1930 era, this No. 215 follows George S. Lewis’s Feb. 10, 1914 patent, a hallmark of Riverside’s external-hammer doubles. The receiver carries clear "RIVERSIDE ARMS CO" and "PAT.
FEB. 10, 1914" markings, tying the gun to its period design and manufacture in the United States.
The shotgun uses a top-lever break action with an extractor (non-ejector), paired with double triggers and external hammers. This traditional configuration provides straightforward operation and control over each barrel.
Its 27-inch barrels wear a solid matted top rib that reduces glare and offers a clean sighting plane. Chambered in 12 gauge with a 2-round capacity, it delivers the classic two-shot side-by-side format.
The hardwood, pistol-grip stock features hand checkering for traction, a slim splinter forend for a classic carry feel, and a black buttplate. Length of pull measures 14.0 inches, providing a standard fit for a full-size side-by-side.
