There isn't one. That model was made in 1963 to 1968. Serial numbers weren't required back then, and having a gun that never had a serial number IS legal.

That model was made from 1963-68. Serial numbers were not required by law on rifles and shotguns until the 1968 Gun Control Act. Does not have one. Yes, it is legal. REMOVING a serial number is not legal, but having a gun that never had one is legal.
