Our Assessment: The history of the L.C. Smith firearms is quite interesting. L. C. Smith formed a partnership with L. H. Smith and W.H. Baker to manufacture a three-barrel gun in 1879. L. C. Smith took over the company in 1880 and in 1884 began manufacturing hammer shotguns. Smith became interested in a new-fangled invention called the typewriter, and sold the company in 1888 to John Hunter. Smith went on to form the Smith-Corona company and became a world leader in the manufacture of typewriters. The L. C. Smith shotguns manufactured by Hunter Arms went on to become some of the highest quality shotguns made in the United States. When Marlin bought the Hunter Arms Co. in 1945, they began manufacturing the same guns under the L. C. Smith Gun Company title. A fire caused destruction of most of the manufacturing capability in 1949 and in 1950, the factory was closed. This is an L. C. Smith Field Grade Featherweight shotgun made some time between 1946 & 1950 we think?  It is chambered in 12 gauge,  2 3/4 ". The shotgun is in about Very Good condition with about 95% of its original finish remaining and nice bores. This would make great addition to any L.C. Smith, double-barrel, American, or really any shotgun collection and would also make a fine field shotgun to this day. Please see our photos and good luck!
