No, not a rimfire scope, just a pre-1974 scope. I have a slightly newer 2-7x28 with a TCH reticle, SN 111853, that has worked well on several different rifles.
Leupold started using an alpha prefix in their serial numbers in 1974, starting with E and ending with Z in 1992, but skipping I, O, and Q.
Leupold started using an alpha suffix in their serial numbers in 1993, starting with A and having gone through V in 2011, also skipping I, O, and Q.
