The Browning Superposed was the last firearm designed by John Moses Browning, which was finalized by his son Val Allen Browning for production to start in 1931. This example of a B1 Superposed is in good to very good mechanical condition, with quite a bit of oil or grease in the action and lockwork as well as some minor corrosion starting in hidden areas of the action and in the bottoms of the engraving. The oil or grease in the lockwork has been seeping into the stock, causing rather prolific oil intrusion, making areas of the stock around the checkering appear constantly wet. Aside from the oil intrusion, the stock has also been modified in the comb, removing material on the left side for a shooter with a somewhat wider face.
