I spoke with Jean Jinks at the symposium in Reno about again offering reproduction certificates for Registered Magnums like the one shown below for my Magnum. Jean will do the lettering by hand and as you can see she does excellent work. These certificates should display well with your ".357" Magnum and should be of interest to other collectors.
The cost of each certificate is $200 with all of the funds going to support the digitizing and indexing of the records of Smith & Wesson by the S&W Historical Foundation.
If you are interested in obtaining a certificate(s), please contact me via a Private Message for details.
