Just acquired this 629-1. The gentleman I purchased it from said he bought in '87 and then returned it to smith and wesson for some custom work. Hi polish, action job, and custom carved stocks. I have not seen stocks custom carved from factory. . Is there such an animal? ? He is "looking" for the receipt from smith and wesson and will send to me if he finds it. I have seen a lot of polished guns, but not of this quality. The trigger and hammer are even polished. Possibly done by smith? I'm not very familiar with work smith did when sending back a gun to factory besides warranty and refinishing. Thanks for any input.
