Is it just me, or in that close up of the markings does it look like the original finish has been sanded off? Theres some dark color on the flats next to the barrel that looks like it may have been a darker color at one time. Might be a good candidate for gaining some finishing experience (ie. shape,sand,stain,finish,seal)or just shoot it! Either way I agree you should thank your dad, it's a great gun.
