Only an estimated 3,000 of these revolvers were manufactured for the Minneapolis Fire Arms Co. in 1891-1892 by James Duckworth of Springfield, Massachusetts, based on Turbiaux's patent before the patent rights were sold to the Chicago Fire Arms Co. who produced a larger version for a few more years. The side plate is marked "THE PROTECTOR/MINN. FIRE ARMS CO." at the center of the removable side plate and "* * PATENTED MARCH 6, 1883" at the center of the frame. Both sides have checkered hard rubber grips.

Fine, retains 50% plus original nickel finish with the balance bright polish mixed with dark grey patina. There are a couple small patches of flaking on the barrel and some light to minor handling marks. The left grip panel has faded brown and both have crisp checkering overall. Mechanically fine.
