I would have it refinished in a high polish as close to factory finish as possible. Maybe that would mean someone other than S & W if they can't do the same high quality job as in earlier years.
I would not sell a shooter grade for anything less than $500. So, I would expect to pay up to $650 or so. These just point and shoot so well. The 3 T's are gravy!
I bought a set or N frame round to square targets from the online store at s&w. They are a bit thinner in the palm than N frame targets, but they work ok. They look alot better as far as I am concerned.
