The Model 20 was first built in 1919 to utilize the expanded production facilities that resulted from World War I. Winchester introduced three different models of single-shot shotguns; the Model 20 was the first of the three. This model has a visible hammer and a top mounted lever for breaking open the action. The Model 20 was the first Winchester to have this type of break-down action. The shotgun was chambered for the 410-gauge 2.5-inch shell and fired from a 26-inch barrel with a full choke. Furniture was a plain walnut pistol-grip stock with a hard rubber plate. Interestingly, the forend had a small lip at the front, similar to later New England Firearms shotguns. The Model 20 was finally dropped from the Winchester product line in 1924 with 23616 examples produced. The example shown here is in fairly good shape. It appears to have been re-blued at some point. There are micro-pits covered over by bluing. Likely, a re-blue was done to protect the metal from further harm by the elements. The wood furniture is in good condition with no cracks, as is the butt plate. The bore is lightly pitted in a couple of spots but nothing serious. This would make a nice addition to a Winchester collection, but it would serve well as a squirrel gun too.
