The factory letter indicates it was received and shipped on September 18, 1886, in .40-60 with a part octagon barrel, plain trigger, half magazine, and casehardened finish. The half-round/half-octagon barrel, half-magazine, and casehardened receiver are special order features. The barrel and magazine are blued, and the other components have a casehardened finish. The walnut stock has a crescent steel buttplate. The barrel is fitted with a Rocky Mountain style front sight with German silver blade and a Winchester sporting style rear sight. The rifle has the third model receiver with integral dust cover rib and is fitted with a late pattern dust cover with serrated edges. The top of the barrel flat is roll-stamped with the two-line legend: "WINCHESTER'S-REPEATING ARMS. NEW HAVEN. CT./KINGS"-IMPROVEMENT-PATENTED-MARCH 29, 1866. OCTOBER 16. 1860." ahead of the rear sight. "CAL 40-60" is stamped on the top barrel flat between the rear sight and the receiver. "40-60" is marked on the bottom of the cartridge elevator. The upper receiver tang is roll-stamped: "MODEL 1876" with a foliate design on either side of the marking. The serial number is located on the lower receiver tang behind the loading lever latch.

Very good plus. The rifle has a crisp mottled brown patina on the barrel and magazine. The barrel surfaces are generally free from pitting and surface rust but have minor handling marks. The case colors on the forearm cap, receiver, loading lever and hammer have a silver-gray patina with some scattered surface discoloration. The buttplate has a dark patina with some-silvered case-colors in protected areas. The walnut stock and forearm are in good to very good condition with scattered handling marks. The markings on the barrel and receiver are crisp. The action is tight and functions well. This is a completely original example of a Winchester Model 1876 Sporting Rifle with scarce, special order half octagon extra length barrel and casehardened receiver.
