I read this thread with interest and believe the S&W 41 I have was shipped sometime in late 1964 or early 1965.....
Regarding value, I am liquidating a collection belonging to a deceased friend's wife and would appreciate your thoughts on a "going price". This 41 has the 5" light weight field bbl and is very lightly used. My friend shot all of the guns he acquired but this one shows no bluing wear, scars or scratches and the wood grips are in VG or better condition. I would rate the overall condition at 98%. Unfortunately, no box, tools or paperwork could be found.... Any assist you can offer with pricing this very nice pistol would be greatly appreciated.
