You might have seen this strange gun in some old movies where it was wielded by both protagonists and villains.
Designed by American firearms designer John Moses Browning (1855 –1926), the Colt Woodsman is a semi-automatic sporting pistol manufactured by the American Colt's Manufacturing Company from 1915 to 1977. The frame design changed over several decades, in three distinct series: series one being 1915–1947 like the pic above, series two 1947–1955, and series three being 1955–1977.
Recently classified as a curio (meaning a rare, unusual, or intriguing object) and relic firearm by the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives or ATF, the Colt Woodsman is an elegant and accurate pistol. It is also light and it's grip is shorter and at a more rakish angle than many pistols today. The design allows for a better trigger pull. The grip angle and sight radius makes for a very pointable and accurate pistol.
