 Although such a transaction would represent significant business for Colt, it appears that the House of Representatives took no action on this proposal, as documents do not mention a purchase of this magnitude by the U.S. Government.Although government sales were poor with Colt's Ring Lever rifles, Colt had more success with his Model 1839 Carbine.This model, produced from 1838 to 1841, lacked a ring lever and featured a more familiar external hammer.
