The included Colt factory letter states this revolver was shipped from Colt's Hartford factory to the Colt London Agency on February 3, 1887. The revolver has the high polish commercial blue finish with niter blue trigger, hammer top and screws. The butt is fitted with a lanyard loop. Grips are black checkered hard rubber with the Rampant Colt trademark in an oval at the top. The top of the barrel is marked: "COLT'S PT. F.A. MFG. Co. HARTFORD CT. U.S.A." in one line. The left side of the barrel is not marked with the caliber designation. The underside of the barrel is marked with the bore diameter "44" and "44 Cal" is stamped on the left front trigger guard bow. The Colt factory letter lists the caliber of the revolver as "44 Russian". The serial number is located on the front of the grip strap ahead of the lanyard loop. The partial serial number, "413" is stamped on the rear face of the cylinder. An assembly number, "22", is stamped on the loading gate. Although the factory letter lists the revolver as being shipped to the Colt London Agency the revolver is not stamped with the usual British proof and view marks. The markings are identical to standard production M1878 DA Revolvers.
