Looking at the pictures it appears that someone has used cold bluing on parts of the receiver. . Tough to say for certain but the receiver appears too shiny to be original finish. . I wouldn't worry over it a good hunting rifle just the same.

These Model 70's are selectively hardened at the receiver ring/locking lug seats, and at the extractor camming surface. Anyone who has glass-bead blasted one of these actions will have noticed this. The localized difference in grain structure and/or surface carbon content is the explanation for the difference in bluing colour. Generally, one has blue these slightly hotter for longer.
