The Winchester model 1911 is worth about $200.00 even in excellent condition. This is surprising as this was the first semi auto shotgun that Winchester made and they made only about 83,000. I have one that was made in 1913. I don't shoot it anymore. It is actually an automatic as it will keep firing as long as I hold down the trigger and I have shells in the tube. This is a malfunction of the action that causes the recoil to fire the next shell in the chamber.
