Good advice from Damascus. To restore it, that is if the barrel is o.k.; which I doubt, would cost more that the guns value. William Palmer Jones made some good guns; which this once was. He specialised to some degree in live pigeon trap guns and was well known in this area. There is plenty of information on this maker and I can post some if you wish. It is a shame it was neglected as it looks as if it was once a good one. No value as it is other than as a wall hanger. I can only give it to you from the English perspective but opinions may differ in the U.S. Lagopus.....
