Approximately 3000 manufactured between 1866 to 1878. "WHEELER'S PAT. OCT. 31. 1865-JUNE 19 1866" marked on top of the barrel chambered for the .32 rimfire cartridge and "AMERICAN ARMS CO. BOSTON MASS" marked on top of the other barrel. The serial number is marked on the butt with the matching number marked inside of the right grip panel. The rear barrel face and frame breech face are marked with the matching assembly number "A28". Superposed barrels manually rotate for loading and firing.

Fine. The barrels retain 40% of the original blue finish with the balance a smooth brown patina. The frame retains 50% of the original silver plating. The grips are excellent with some minor scratches and some light nicks on the bottom edge. The bottom has some very light varnish flaking. The markings are clear and crisp. Mechanically fine.
