Welcome to the forum!
The cost of refinishing would be prohibitive in my opinion. Plus you now have a refinished gun and thus not original.
I would shoot, carry and enjoy. A good friend (ret KSP det) carries his Detective Spl on occasion for a bit of nostalgia aka old school.
Check the completed gun acution sites for an index of current market value. To me, $750 is a little more than I would care to invest.
