Manufactured in 1873. This four shot version is known as the "Cloverleaf" due to the shape of the cylinder when viewed from the front. The cylinder, ejector rod and hammer are finished in gold and the frame and barrel silver. The top of the barrel is marked "COLTS HOUSE PISTOL/HARTFORD CT. U.S.A." flanked by Maltese crosses and the top strap is marked "PAT. SEP.19, 1871." The matching serial number appears on the butt and bottom of the barrel. The sides of the barrel, each cylinder chamber frame and top of the back strap are engraved with a floral scroll and punch dot pattern and very well could have been executed by the hand of master engraver Louis D. Nimschke. There is a blank panel on the left side of the frame and blank banner on the right side. In addition there are scallop patterns on the top and sides of the top strap, lower and front portion of the frame and on the back strap. There is a zigzag pattern in each cylinder flute. Pinched blade front and frame notch rear sights and fitted with smooth pearl birds head grips.

Very fine plus. The barrel retains 95% plus original silver plating, darkening with age in some areas. The frame retains 35% original silver, mainly in the protected areas, also darkened with age. The ejector rod and hammer retain 30% of the original gold finish all in sheltered areas. The cylinder retains traces of original gold finish concentrated in the flutes with the balance having a smooth mottled patina. The grips are excellent with a couple of minor dings but other wise have a nice grain pattern. The engraving and markings are crisp and clear. Mechanically excellent. A rare factory engraved Cloverleaf in very fine condition.
