There is no way to tell with only a serial number. As surprising as it may be, there are multiple guns that can have the same serial number- different makes and models. If you give us a complete description, we may be able to help. Good questions= good answers.
Serial numbers are not unique between makers. Impossible to answer.
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.

Impossible to answer. Serial numbers are NOT unique to only one gun in the world- or they would be REALLY long numbers.
Serial numbers were not required before 1968. Check the receiver, barrel.
It may not have one. Rifles and shotguns made prior to 1968 were not required to have serial numbers.
No sn data available.
