That's a nice looking gun, and in that pic the grips don't look like they need any attention. We have a forum member here that we all use for grip refinishing named VM. He does outstanding work for very reasonable prices, has fast turn around, and you will be happy with his work if you choose to use him.
We also have a forum member here named jcelect that restores the interior of these case to better than new condition. Most of us use him too. Again, very reasonable and you won't be disappointed.
The pic makes my gun look better than it is I think. It is nice though, especially for its age. There are lots of members here with much, much, finer examples than any I own, but thanks for the compliment.
Merry Christmas!
