This is an extraordinary Winchester Model 1866 musket that was manufactured in 1877. This Model 1866 musket has the distinctive 27 inch round barrel with 24 inch magazine and 17 inch walnut forearm secured by two barrel bands. A bayonet lug for a sword bayonet is mounted on the right side of the front barrel band. The stock has carbine style brass buttplates with sliding trap door. Factory sling swivels are mounted on the upper barrel band and stock. The barrel has block front sight base with steel blade, and folding leaf rear sight with 900 yard center notches and screw stops for the elevation bars. In addition to the distinctive Model 1866 brass (gunmetal) frame and carbine style buttplate, the musket has a blue barrel, magazine, barrel bands and loading gate, with casehardened hammer, trigger and lever. The straight grain American walnut stock and forearm are oil finished. The top of the barrel is roll stamped with the two line legend "WINCHESTER'S-REPEATING-ARMS. NEW HAVEN. CT./KING"S-IMPROVEMENT-PATENTED-MARCH. 29. 1866. OCTOBER 16. 1860" between the lower barrel band and the rear sight. The serial number "148256" is stamped on the lower tang behind the trigger. This musket is consecutively serial numbered to the previous Model 1866 Musket.

Excellent to near new showing only very limited storage wear. The barrel, magazine and barrel bands retain 98% or more of the original blue finish. Nearly all of the niter blue finish is present on the loading gate, the rear sight spring and the rear sight elevator bar. The hammer, trigger and lever retain 99% of the muted case colors. The brass frame is exceptional. The side plate joints are perfect and the buttplate is in the same pristine condition as the receiver. The barrel legend and serial number are perfect. The wood is excellent plus and show only slight handling wear. Consecutively serial numbered Winchester rifles of any type are scarce and desirable.
