I did find this at pre64win.com:

511111 - All rifles with serial numbers below 66,350 (pre-war), except .300 H&H and .375 H&H
511112 - All rifles with serial numbers above 66,350 (post-war), except .300 H&H and .375 H&H
511114 - .300 H&H and .375 H&H magnum rifles with serial numbers above 66,350 (post-war)
511115 - .300 H&H and .375 H&H magnum rifles with serial numbers below 66,350 (pre-war)

Perhaps its of some help

Your base is the same as this one:

Its called a Redfield 70 A "MAG".... That is written on the bottom of the mount:
