The first Ruger Pistol ( Mark I) was introduced in 1949 and have always bore a passing resemblance to the famous German Luger pistol of both world wars, though the action more closely cosmetically resembles the Japanese Nambu.
are you sure its a mark III? The Mark III was only introduced in 2004. The Mark II was in froduction from 1982 until 2004 when the Mark III came out. The Ruger Mk I was Bill Ruger's first firearm and was introduced in 1949 and discontinued in 1982 with the advent of the Mark II.
