Type III "Split Breech" civilian carbines, such as this one as evidenced by its lack of an inspection cartouche on the stock, were part of the last batch of approximately 1,000 manufactured using leftover parts, dies, and machinery that was returned to E. Remington & Sons after the completion of the U.S. government contract deliveries by Savage Revolving Arms Co. on behalf of Remington. These were advertised in the catalog of 1866, with many sold and used out West. Thirty split breech civilian carbines like this example are known to have been purchased by Nelson Story Sr., who was a pioneer, Montana entrepreneur, cattle rancher, miner, vigilante, and a notable resident of Bozeman, Montana, just prior to his famous 1866 cattle drive from Texas to Montana along the Bozeman Trail with approximately 1,000 head of Texas Longhorns; the first major cattle drive from Texas into Montana. Features a pinched blade front sight, notch rear sight with folding leaf graduated to 500 yards, two-line Remington address and patent markings on the upper tang, and saddle bar with saddle ring on the left of the frame. "C.G.C." (Charles G. Curtis) inspection initials (leftover military contract part) marked above a "T" and "P" proof on top of the barrel (hidden by the barrel band). Serial number "1279" marked on the left front surface of the frame and "286" marked on the bottom of the barrel at the breech. "US" marked buttplate tang (leftover military contract part).
