In the early 19th century Manton invented the tube (or pill) lock, an improvement over Alexander Forsyth's scent-bottle lock [REF].
Although more reliable than Forsyth's design and adopted by many sportsmen during the Regency period, (and a variant for the Austrian army),[REF] within a short period it was overshadowed by the percussion cap which was adopted by the armies of Britain, France, Russia and America to replace the flintlock [REF].
