Only about 100 of an estimated 600 manufactured by the famed Browning Brothers in Ogden, Utah, have survived. They were manufactured based on designs patented in 1879 by John Moses Browning when he was in his early 20s. Many of the rifles have aspects that differ. This example has a short blade front sight, a Winchester Model 1876 notch and folding ladder rear sight, double set triggers, a smooth forend and straight grips stock, a cleaning rod under the barrel, and has the markings "BROWNING BROS. OGDEN, UTAH, U.S.A.," "PAT. OCT.7.79. 45 70," and "366" on the top of the barrel. The action is similar to the later Winchester thick side high wall version of the Model 1885. The hammer is cocked when the lever is closed. The reputation of the early Browning rifles set Browning on a path for greatness. After receiving $8,000 in return for rights to his single shot patent from Winchester, Browning, in partnership with his brother who ran much of the business end of things and also contributed to designs, developed designs that led to nearly every influential Winchester of the late 19th century as well as various firearms manufactured by other companies including the Hi-Power pistols, various semi-automatic pistols manufactured by Colt including the ever popular Model 1911, machine guns such as the Model 1895 and .50 Caliber Browning Machine Gun, and pump action, semi automatic, and superposed shotguns. Nearly all of the significant firearms of the last century are based in some way on a Browning invention other than revolvers and bolt action rifles. Many of Browning's designs helped lead to victories for the U.S. and its allies in conflicts around the globe throughout the last century and some remain in use to this day.
