selling a S.S.# tagged shotgun

[Innovator]

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:confused:

16" barrel gun is illegal without the proper tax stamp - good for a Federal crime/felony. Minimum barrel length on a shotgun is 18", 26" overall for the Feds. Some states have greater restrictions

Maybe OP meant 16 gauge?
If it is 16" it might be okay in canada or elsewhere but would require a federal stamp as stated above.
