My Records indicate that your model L.C, Smith, was one of the later production hammerless shotguns, mfg'd in Fulton NY between 1914 and 1951. The finishes were case hardened or blued with walnut checkered stocks and forearm. Stocks were either semi-pistol grip or pistol grip configurations. The various models differ as to the degree of ornamentation and the quality of materials and workmanship.
