This is an example of a Winchester Model 1886 chambered in the rare 50-100-450 caliber manufactured in 1908. The top of the barrel is marked "-MANUFACTURED BY THE-/- WINCHESTER REPEATING ARMS CO. NEW HAVEN CONN. U.S.A. -" ahead of the rear sight and "50-100-450" at the breech. The Winchester oval proof is marked on the top barrel flat ahead of the caliber marking and on the top of the receiver at the breech. The upper tang is marked "MODEL 1886/-WINCHESTER-/TRADE MARK" and the lower tang is marked with the 1884 and 1885 patent dates directly behind the trigger and the serial number behind the lever. The barrel is fitted with a dovetailed Winchester Express front blade sight with a silver bead and a three leaf (two folding, one fixed) Winchester Express rear sight. Blue finish with casehardened hammer, lever and buttplate. Mounted with a smooth walnut forearm with steel end cap and straight grip stock with a crescent buttplate. The powerful 50-100-450 Express cartridge was introduced by Winchester for the Model 1886 rifle in 1895 but was not popular with American hunters and was discontinued in 1910. Model 1886 Express Rifles chambered for the 50-100-450 cartridge are extremely rare.
