It is estimated that only a few thousand of these revolvers were manufactured in the 1880's. The top of the rib is marked with the two line address/patent dates without reference to the Hopkins and Allen name. The revolver is nickel with a blue trigger guard and features a blade front sight and a notch canal rear sight and smooth pearl grips. It is engraved with simple scroll engraving covering the sides, top strap and cylinder flats. The left side of the frame also has a cabin in the woods. Smooth pearl grips. It has an unusual mechanical operation. When the hammer is cocked, you push a button located just ahead of the trigger and the barrel pivots to one side, another button located on the barrel lug is pushed and the barrel assembly and cylinder can be removed from the frame.

Exceptionally fine with 85% of the original nickel finish remaining with very minor wear on the muzzle, front of the bright polished cylinder and backstrap with minor scattered scuffs and dings. The trigger guard is now a smooth grayish patina. The pearl grips are excellent showing nice shadow colors. The action needs a minor adjustment, it hangs up when cocking for single action, however works fine when pulling the trigger on double action.
