The frame of this very interesting pistol started life in early 1943, at the height of World War II, and was manufactured by Remington-Rand. There is little doubt that the frame of this pistol and most of the smaller components saw heavy use for the following two years in the war effort against either the Germans or the Japanese. The frame then found its way into the Korean War, either as a complete pistol, or merely a frame transferred to South Korean forces. At some point during its time there the pistol was fitted with a barrel and slide that were manufactured by the Pusan Jin Iron Works, a South Korean factory known for producing copies of 1911/1911A1 pistols, often utilizing American made parts. The Pusan pistols are often noted for being fairly low quality compared to their American counterparts, but are generally fully functioning copies unlike many of the Vietnamese made copies. This example is incredibly rare in that it utilizes a complete American made frame, while most examples usually only show a few scattered small parts of American origin. The left side of the slide on this example shows the standard Pusan Jin marking and is numbered "3/7" internally. The Korean made barrel is also numbered "3/7" on the bottom, and "3/7" has been stamped internally on the frame, indicating that this slide and barrel were specifically fitted to this frame. The left side of the frame has the "FJA" inspection mark and "P" proof, while the right has the standard U.S. property, serial number, and model markings. Apart from the slide and barrel, all components appear to be American made. It is fitted with Keyes Fiber checkered grips and a full blue "L" marked magazine.
