When I got it, it had almost 1/8" of varnish on it (seriously) it was everywhere. Floor plate, grip cap, butt pad, and looked like someone had applied it with a pine top. I stripped it, and applied 7 coats of true oil, (no stain) and hand rubbed it. I bead blasted the floor plate and trigger guard, and painted them. I am not original owner,It shoots great. Date of mfr could be 1979 or 1980, #74-58xxx. No open sites.
