This unserialized pistol is one of less than an estimated 100 prototype pistols based on the Model 1900/1902 rifle action and manufactured during the early 1900s as Winchester explored the idea of making a single shot pistol based on the actions of these popular rifles. It has standard Model 1902 rifle markings on the barrel, Winchester factory oval proof on the barrel, and is fitted with Lyman beaded blade front and adjustable notch rear sights. The stock is carved with floral, geometric, and burst motifs, and there is a carved "MW" monogram on the butt of the grip. Madis discusses these interesting prototype pistols in "The Winchester Book". It is possible that some of these prototypes were retained by factory employees. This specific pistol is very similar to another example previously sold by Rock Island Auction Company which was presented to U.S. Army Brigadier General Abel Davis, recipient of the Distinguished Service Cross and Medal for actions in World War I.
