REVOLVER

                                    The first successful revolver, the prototype from which all later revolvers are descended, was patented by the American gunsmith Samuel Colt (1814 - 1862). He also made riffles and shotguns with revolving chambers, but his first factory went bankrupt and it was not until the 1850s that Colt had a big success with his Navy revolver. His guns were used by the army and the navy in the American civil war.
