Agreed, they are very special rifles. Yours looks like a good one and is interesting because it has one of the early minor stock change transitions. About the first year (ca 1951-2) of the stock comb "hump" in the sporter models for better eye alignment with a scope.
Anyone interested in these should really consider getting Rule's book- The Rifleman's Rifle.
For comparison, here's the butt stock of a 1950 standard sporter Win 70.
