This is a unique Winchester vest pocket flash light from the 20’s. It is marked Winchester Trade Mark Flashlight. On the side it is also marked Pat. 8/17/1920, 11/5/1921 and 7/4/1922. It is also marked Made In The U.S.A. The model no. is 7031 which is marked one the flashlight. We found this model in an old Winchester Collectibles Book. It does not have a battery, so we are unable to test it. The inside is very clean.
