You have a Saco Lowell M14 National Match barrel made in July of 1965 that has been Magnetic Particle inspected and Proof Tested.
It is an excellent barrel, but the inside condition is far more important than the outside condition.
Many of these barrels looks new, but they have been WELL used and re-parkerized. You need someone who has a set of 7.62x51 guages to check the throat erosion (TE) and muzzle wear (MW).
