The Martini-Henry is a single-shot lever action breech loading rifle that fires the .577/450 as its ammunition and was developed in 1870, as the main infantry weapon for army of the British empire, in many colonial wars of the late 19th century, until it was replaced by the Lee-Metford in its roles, as 20th century began. Its name came from the two source: Friedrich von Martini, the Swiss designer who invented its lever-activated falling-block action, and Alexander Henry, the Scottish gunsmith who developed the weapon's rifling.
