Those who can't confine themselves to answering the question will sometimes answer the question you're going to have later. Take a poll, weed out the extremes of cost, downtime, exotic and potentially hazardous "treatments" (stock floating in a sea of acetone IS one, in case Ted was overly tactful and you missed it). What is left is the majoritarian get er did approach which usually involves a "spruceup" with the shinola at hand. Amazing what a bit of shoe polish and a coat of Ballistol can do. I'd start by scrubbing the mud off the bitter end of the pad and clean/lube the action, hingepin, and bolting, scrub out the bores no matter how good they look. Don't make the gun into those birthday present sweaters I used to get from my dear Auntie. "I have to take it back to add the right sleeve and finish the neck," she said, "but I thought you'd want to see it before I do." Last time I ever saw most of them. A present is not a promissory note.

PS: Heating the stock head will bring some of that gunoil out of the pores and whiting (chalk) will absorb it. You will need several "iterations" of that also so maybe just shoot it $300 worth is the advice most easy of accomplishment.
