This is an excellent example of a rare Colt Model 1890 Gatling Gun mounted on a two wheel carriage. The Model 1889 was essentially an improved version of the Model 1883. In 1889 Gatling returned to the well proved classic design of the exposed barrels as used in the Indian War campaign. Some of the improvements included a device called the "Murphy Stop", (a cocking switch) a new type carriage and the hooper was interchangeable with the special Bruce feed or use of the old style gravity feed magazine. Similar to the Model 1883, the Murphy stop allowed the gunner to disengage the cocking mechanism while unloading the gun and during training exercises without ammunition. The control knob was in a more convenient location on the cascabel plate and operation was more positive since the knob had to be pulled out as well as turned. This model features ten 32 inch 45-70 barrels, (5 inches of the muzzle end are octagon), has an overall length of 49 inches and weighs approximately 200 pounds without the carriage and has a rate of fire of 525 rounds per minute. Essentially all models manufactured from 1889 to 1892 were identical. The breech end of each barrel is numbered 1 thru 10, proofed "V/P/eagle head" and "R.A.C." (Rinaldo A. Carr) inspected. The breech end of the breech housing is marked with the corresponding barrel number. Each barrel toward the breech end is marked with the matching assembly number, "14". The top of the frame ahead of the barrels is also marked "R.A.C." and "14". The sights are mounted on the right side of the frame. The rear of the magazine feed port is marked "PATENTED/FEB. 11, 1890/R.A.C.". The top rear of the breech housing is "R.A.C." inspected over engraved "Gatling Gun/Patented/Manfd at/COLT'S ARMORY/Hartford Conn. U.S.A./MODEL 1890/No 505 CAL 45/SEB"(Capt. Stanhope E. Blunt). The breech end face of each bolt is marked with a "P". Inspection mark. The gun is mounted on the original iron yoke. The U.S. Army purchased 18 Model 1889 Gatling Guns (serial number 492-509), with this gun being one of those, 17 Model 1891s and 18 Model 1892s. These were the last 45-70 Gatling Guns ordered by the U.S. Government. The gun is mounted on a barracks green painted carriage with an equipment/ammunition box mounted on either side of the gun and iron banded wooden wheels. The end of each wheel hub is cast with the manufacturer Archibald Wheel Company, Lawrence, Mass. The Gatling Gun had a huge impact on the battlefield and changed the face of wars forever. Accompanying the gun is 2 copies of the book "The Gatling Gun" by Wahl and Toppel and "The Gatling Gun" by Beck.

Extremely fine. The breech housing remains bright and the very fine armory bright barrels have a smooth gray patina. All of the markings and engraving remain crisp and clear. The carriage was repainted some time ago and almost all of the paint remains with some flaking on the wheels and top of the equipment/ammunition boxes. Mechanically excellent. The iron hardware retains all of the black paint. The Magazine is absent. A very nice, rare U.S. Government Model 1890 Gatling Gun, one of only 18 purchased by the U.S. Government and one of the last 45-70 caliber Gatling Guns purchased by the U.S.
