Less than 1,000 of these revolving rifles were estimated to have been manufactured c. 1866-1879 per Flayderman's Guide. The factory conversions to rimfire would have been towards the latter years of that range. This example is number "503" and has the matching serial number on the bottom of the barrel at the breech and on the removable breech plate. The breech plate and back of the cylinder also have the conversion/assembly number "250." The barrel has a golden Beach combination front sight and an elevation adjustable sporting rear sight. The upper tang is also fitted with a peep sight. The barrel and cylinder are blued. The loading lever and frame are casehardened, and the trigger guard and buttplate are nickel plated.

Fine with 20% original blue finish, 70% original case colors, traces of original nickel plating, and mostly smooth gray and brown patina on the balance. The stock is also fine and has smooth oiled finish, some cracks in the toe, and minor marks and scratches. Mechanically excellent.
