Fion MacCumhail, my pre-64 Model 70 in .30 Govt 06 is 25XXX and was made in 1939.
I know the original owner took this rifle to Africa, and it was mounted first with a Redfield aperture sight. Later, a Lyman Alaskan (3/4" tube) was mounted over that, and it still wears the Redfield, snuggled up under the ocular bell of the scope.
The varnish on the stock is missing where hands have rubbed it off, and the finish shows the effects of 75 years of hard hunting. I call that "honorable scars."
