I bought my son a Fulton Special 12 Ga DBL serial number S 87263. Hunters Arm Co Inc. M'F'R'S' Fulton , NY USA. What is this gun worth and should I let my 13yr ols hunt with it or should I put it up.. Please Help I need some guidance .. I have went to the web site and studied about this gun. I understand the make and the years it was made.. I know it was sold in 1937 for $31.00.
