#154304 F under number. 1907? HUNTER ARMS Co. MAKERS,FULTON N.Y. Found at my grandfather's. House was unoccupied at the time, moisture got to it Unfortunately cleaned it myself before I knew it's value. It was roached badly. Spotted corrosion inside barrel. Serious surface rust starting on the outside. All in all, mechanically, sound. Tight quality fit saved the break. Corrosion in barrel is concern. Hope the cleaning didn't do too much harm? Thanks, M.Turri
