Manufactured from 1876 to the 1880s these revolver were known as the "Army Revolver" and had a total production of several thousand. The top of the barrel is marked with the one line Merwin Hulbert address followed by seven patent dates and the left side is marked with the one-line Hopkins & Allen address. The serial number is marked on the butt and the matching assembly number "5735" is marked on the rear face of the cylinder, cylinder pin, barrel lug, left side on the frame toe under the grip and hand marked on the inside of the right grip panel. The left side of the frame is absent of any caliber markings. Integral blade front sight, frame notch rear sight, open top frame, scooped cylinder flutes, nickel finish with casehardened hammer and nitre blue trigger and fitted with checkered mottled colored hard rubber grips with a lanyard ring on the butt.

Excellent. The revolver retains 99% original nickel finish with some light scattered flaking/blistering and some wear in a couple of the cylinder flutes. The hammer retains most of the original bright case colors and much of the original bright nitre blue finish remains on the trigger. The grips are excellent. The markings are crisp and clear. The action is excellent.
