This an example of one of 124 Colt Single Action revolvers that were shipped to Mexico in two shipments, one in April and one in August of 1908 through M. Hartley Company of New York, New York. All of the Single Action Army revolvers had the 4 3/4" barrel and were chambered for 38 W.C.F. These revolvers were engraved "E. de Mex" (Estados de Mexico - States of Mexico), on the left side of the barrel ahead of the caliber marking. Everything else is standard on the revolver. The top of the barrel is marked with the short two-line address, caliber designation "38 W.C.F." on the left side and the left side of the frame is marked with the two-line, three patent date marking followed by the circled Rampant Colt. The matching serial number appears on the frame, trigger guard and backstrap. Blade front and frame notch rear sights, blue finish with casehardened frame and hammer and fitted with checkered hard rubber grips with the Rampant Colt in an oval at the tops.
