Collier Second Model Five-Shot Flintlock Revolver ca. 1820 Patented by Elisha Haydon Collier The Collier pistols design was far ahead of its time. Its technology, construction, and appearance anticipated Colt percussion revolvers that were developed and manufactured in the United States two decades later. Patented in England on November 24, 1818 by Elisha Collier, an American engineer from Boston living in London, the mechanism features a hand-rotated five-shot cylinder and a priming powder magazine incorporated into the steel. Collier himself was not a gunsmith and did not invent the action. The action was originally conceived by Captain Artemas Wheeler (1781-1845) of Concord, Massachusetts, who patented it in the United States on June 10, 1818.
