This is a double barreled 12 gauge hammerless shotgun made by Baker Gun Co. Named the "Batavia" after the town it is made in back in the 1920-30s. The barrels are 30 inches long, with Full & Modified chokes. There are areas on the barrel in which the finish has worn off, and I've tried to show that in the pictures. Chambered for 2 3/4" shells.
