This is a scarce Winchester accessory that has become almost impossible to find...a rare Winchester Model 1892 Bore reflector. Back before the days of battery-powered bore lights and scopes...this was the original Winchester factory accessory to view the bore of your lever action rifle or carbine. They were sold out of the Winchester catalog for .50 cents during the late 19th and early 20th centuries. Today, you could go to the World's largest Gun show in Tulsa, the Great Eastern in Louisville, Baltimore, and the Las Vegas Arms show and chances are good you won't find one of these little devices. Trust me on this one guys, I've looked and looked. Over the years, I've only seen a handful of these. The body is made of brass and the back is wood so it doesn't scratch up the face of breech bolt. There is even a slot in the wooden end to fit over the protruding extractor on the face of the bolt...pretty clever, huh? The devices is simple. It incorporates a slanted mirror that allows the viewer to observe the bore of their Winchester rifle by simply opening the action and placing the reflector into the breech. The side of the instrument is marked "WINCHESTER REPEATING ARMS CO. MODEL 1892." While they're called the "Model 1892", they'll work fine in almost any lever action Winchester from Models 1873, 1876, 1886, 1892, 1894, up to Model 1895's as well as many other guns. If you're tired of having to wad up pieces of paper or holding shiny objects in the breech of your Winchester just to see the bore...this is a rare and collectible solution to your troubles. Good overall condition with no dents or damage to the brass and wooden body. Nice sharp markings. Mirror has 90% strong original silver with some tarnish down along the bottom edge..fairly minor.
