In order to dispose of some of his inferior arms from the second Connecticut state contract, Whitney assembled at least 1,300 bearing a fictitious Old English lock stamp Manton" forward of hammer and date "1862" on its tail. In most respects, this arm resembled U.S. M1861 rifle-musket complete with 3-groove rifling in .58-caliber 40" barrel with typical Whitney letter/number code near the muzzle (often marked "G.W.Q." on its left flat). Nosecaps, in typical Whitney style, were cast from pewter instead of being formed from malleable iron. Rear sight closely follows M1861 pattern, but lacks the step on its side walls since it utilized a simple pierced leaf instead of compound double leaf of M1861 rifle-musket. These arms were disposed of in the New York City market after 1863 Draft Riot and issued to New York National Guard.
