I have a Stevens model 37 that my dad found in a sand dunes 30+ years ago and that is all I know about the gun. It is a single shot bolt action gun. It has a 23 inch smooth bore barrel. There is a 23 stamped on the side of the barrel near the stock. In the chamber under the bolt, there is a 7 2 stamped. Does anyone know where I can find info about this gun? THANKS!!
