Savage 311 side-by-side double shotguns are a utility/entry grade shotgun from days gone by, often fondly remembered by aging Baby Boomers (look up "nostalgia" for further info about that). This very solid shotgun was cheaply and plentifully made by the Savage Arms Company in numerous grades and sold under various names (Savage, Stevens, Springfield, Sears & Roebuck, etc, etc). The stamped checkering was artfully executed by a large machine in Massachusetts, then a coat of stain varnish was lovingly applied in a spray booth. After basking in the warmth of the artificial sunshine inside the drying booth, the wood was lovingly screwed to the metal parts with a large electric screwdriver. The vent rib is a clue to the late date of production of your shotgun, because by the 1970s it was virtually impossible to sell any shotgun without a gloss finish and a vent rib. These little gems generally sell for $350 to $600 or so.
