This is a Winchester 20ga that is a one off. It is a model 12 and the one never struck so it is a model 2 20ga made between 1947-49 I can't lock down the actual date because of records and what this is but I have spoken with Winchester and that's the time frame from the ser#. It was produced as a riot gun. It is a 20ga modified bbl with head sight. Minus the scratches in the forend that are not deep at all, I'm thinking a ring or being moved in a safe. This is a one owner gun as well. It is in excellent condition and a very cool firearm. Please email for more pictures or questions
