Looks nice in low rez. Butt stock grain looks nice as well and lots of evidence of carrying in the woods at the breech, as no butt swivel seems evident. (They came that way sometimes)
Bore condition?
IFF excellent, hunt down a Lyman 48 (WJS but check that out as I am away from mine) and get your gunsmith to mount along with higher fore sight.
If not put two pegs on the wall, and mount ceremoniously, with scotch in hand, as it is not worth the fuss and $muss of gearing up for accuracy.
Best of luck.
