You seem to have a Model 1200 Super, from the late 1960's or early 70's, which utilized a version of the Mauser 98k action.
(Two different opinions - That's what makes a horse race.
)
I have a Euro-only Safari version in .30-06, which a serviceman brought back in a dufflebag around 1960, that's pretty accurate with all bullet weights from 150-180 grains. (That doesn't make me a P-H expert, though)
