I "inherited" about 5 years ago what I am told in a Letter of Authenticity from S&W is a .38 S&W Special Military & Police Model of 1905 Third change. According to the info in the Authenticity Letter, this "modification occurred in 1909 and was produced until 1915". The letter also stated when it was shipped from the factory (1913) and where it was delivered to (New York, NY). I would really like to get more information about the gun but SWH can't help since their records only go back to 1920. Family stories have this gun coming from an Uncle who was on a major city police force to my Dad. Any family members who would know more information have all passed. The S&W letter also suggested that the grips are aftermarket and it appears the revolver has been refinished. Any help to narrow down the history or where to look or research would be greatly appreciated.
