This is a very nice example of a late production Winchester Model 1866 fourth model saddle ring carbine that was manufactured in 1889. There were only 300 rifles and carbines actually manufactured that year. The 20 inch round barrel has two barrel bands with a block iron front sight and folding leaf rear sight. The left side of the receiver has a staple-mounted saddle ring. The top of the barrel is marked "WINCHESTER-REPEATING-ARMS NEW HAVEN CT./KING'S-IMPROVEMENT-PATENTED-MARCH 29. 1866.OCTOBER 16. 1860", between the barrel band and the rear sight. The top of the rear section of the barrel is marked "44 RF". The serial number is located on the lower receiver tang behind the loading lever latch. Blue barrel and magazine tube, casehardened hammer and lever. It is fitted with a standard walnut buttstock with a steel buttplate, usually found on later production Model 1866 rifles and carbines along with a standard forearm.

Good, with a nice even mustard brown patina on the receiver and sideplates. The barrel and magazine tube are an even brown patina over light scattered pitting. The markings are clear and distinct. The stock and forend are also both in good condition with a nice dark matching finish overall, with minimal handling marks with the stock having been lightly sanded and restained years ago. A good example of a late production Winchester Model 1866 saddle ring carbine.
