John Krider (1813–1886) of Philadelphia apprenticed under Prosper Vallee starting in 1826 and purchased his master's shop on the northeast corner of Second and Walnut in Philadelphia by 1839 and ran it as a leading gun and sporting goods store. Krider was also the maker of the prototype LeMat revolver. The shotgun features a Damascus, octagon to round, smoothbore barrel with a bead front sight, "PHILADELPHIA" marked on top of the breech section, casehardened breech plug with floral engraving, and Birmingham proofmarked on the bottom flat. The bar-in-wood flat lock is signed "J. KRIDER." and has wavy line borders and scroll engraving. The furniture features coordinating scroll engraving. The round knob pistol grip stock has fine multi-point checkering and a 13 1/4 inch length of pull.
