Manufactured in 1878, this revolver was inspected by Henry Nettleton and the butt is stamped "U.S.I.D.". The marking was that of the United States Interior Department and a large number of these nickel plated Cavalry Models were issued to Indian Scouts. Nettleton inspected a number of these nickeled models starting at serial number 47,000 to about 50,400 with the largest concentration coming in the 49,000 to 50,400 range. These nickeled Cavalry Models are discussed in detail in Kopecs "A Story Of The Colt Single Action Army Revolver". On page 250, second paragraph, the author states the following, "In our studies over the past several years have consisted of a thorough survey of over twelve hundred U.S. Colt Single Action Revolvers, existing today in collections throughout the world. Only one revolver surveyed is stamped "U.S.I.D." on the butt strap. The top of the barrel is marked with the one-line address and the under side is marked "P/H.N." directly ahead of the cylinder pin. The left side of the frame is marked with the three-line patent dates followed "U.S.". The loading gate is marked with the assembly number "1102". The cylinder is marked with the letter "P" and "H.N.". "H.N." is also marked on the bottom of the frame over the serial number, below the serial number on the trigger guard and on the top of the back strap. The full matching serial number is marked on the frame, trigger guard and back strap with the partial number "9391" on the cylinder. "45 Cal" marking is present on left side of forward trigger bow. "Bulls-eye" ejector rod head, blade front and frame notch rear sights. Fitted with a smooth one-piece walnut grip with a faint oval cartouche on the bottom of both sides and "H.N." on the bottom right side. The copy of the factory letter verifies the caliber with barrel length, finish, grips as "Not Listed" and that it was delivered as 1 of 150 to the U.S. Government Inspector at the Colt factory on August 12, 1878.

Very fine. The revolver retains 80% of the period nickel finish with some scattered minor flaking and areas of smooth mottled gray patina. The grip is very good with some moderate wear on the lower edges, a few small minor dents on the bottom right side and a few minor dings and handling marks. The markings are crisp and clear. The action is excellent.
