My father had this gun in his closet for many years never touching it. Its a Westernfield M172B-12GA-C-LECT-CHOKE it a bolt action gun made by or distributed by Montgomery Ward not sure which but the name is on the barrel. The stock is in great shape but the barrel and bolt have some minor spots or surface rust. I'm not sure if its worth anything or the time to reblue the barrel and clean up the bolt. Can anyone help?
