Looks like an older gun then that, with the Jones underlever, condition does not look good from the pictures, again, this is hard to tell from where I sit. The action looks loose from 1 of the pictures, I can't see the barrel inside and out. Without the gun in my hands or better pics./description, it's a wall hanger and worth $150 at most. IF it is/was in good condition ie: action tight and good lockup, very minor barrel pitting inside and out, ribs in place solidly (could be fired), it could be worth $300. If it were a major(famous) maker, it could be worth even more....IMHO
