I'm new to this forum. Hope I can get some info on a shotgun left me by my father-in-law. It's a Baker Batavia Leader. The serial # is 1203 F. I've owned the gun for about 20 years and believe my father-in-law bought it in the 1940s. A fellow in town is interested in buying the gun but I have no idea of its worth & could use some help in this respect.
