I was given a 16" double barrel coach shot gun as a gift years ago..Cousin has long passed on and I never thought of a "paper trail" on the gift. My question now is: can I trade , sell or pass on ( to family ) this shot gun that has his S.S.# on 4 diffrent locations on the weapon. What happens if I am stopped by "the man" traveling to a range with this weapon. I have no proof it is now mine. What are my opitions
