Brian is right with the serial numbers. One was factory and one was territorial. I got a CLLE target rifle from the Fultons MANY years ago and also got a letter from Robin Fulton explaining the two serial numbers. Apparently the CLLE was one of his personal target rifles which he had decided to sell ....that has to be 40 years ago at least!!!!!! Now to find the letter to put with the rifle when it is sold after I pop off. A little providence never hurt any piece.
