Thanks a lot for all the information, friends.
Didn't realize it was that old.
I have no plans to refinish it or change grips. I prefer to keep it the way Grandaddy liked it. I still have the holster too.
He had several old S&Ws besides this one: a .44 Special and a .22LR that I gave to my cousin, and a snub .38 my daughter now keeps.
