This Colt M1911A1 was manufactured by Union Switch & Signal, a railroad signaling equipment company converted to wartime pistol production, one of several unconventional American manufacturers pressed into 1911A1 production to meet the US military's enormous WWII demand for standard-issue sidearms. Union Switch & Signal's relatively brief and limited production run makes its pistols notably scarcer than those from Colt's own primary wartime output.
