I have inherited my Grandfather's L C Smith dbl barrel hammer 12ga. SN# is 174443 w/ a F under the number. On the top right barrel is stamped Royal Steel , on the left is THE HUNTER ARMS CO. MAKERS FULTON, N.Y. L C Smith is on the side plates. There is checkering on the grip and fore-end. Gun looks to be in good shape. All parts look present. Any information and possible value for this gun would be greatly appreciated.
