Hi I'm Matt I have recently inherited a Scottish made 12 bore box lock shotgun. The engraving on the gun says D&J Fraser it was one of a pair and I have the original case. Unfortunately the case is not in the best of condition and I only have one ocomplete gun but I do have the barrel of the second. The label in the case is very faded but says John Fraser gun manufacturer edinbourgh . Does anyone have any information on these guns and any idea of its value
