I have purchased the book and am very pleased with it. I am trying to put together a uniform for shooting in our club. I have most of it but have not had any luck finding a correctly styled reproduction hat for the 1898-1900 time period. I am also a collector of Smith & Wesson 1899's. I know the US Navy purchased 1,000 of them and I have three of those pistols. My favorite one to shoot is S&W serial #5170 which caries US Navy #34.I have been searching for records to collaborate the S&W serial #'s with the US Navy #'s without any luck so far. Anyway, I saw that you had the Colts listed as being used by the USMC, but did the USMC also use the Smith & Wessons model 1899/s the US Navy purchased? If so, are there any pictures of that? Love the book and I use it as a reference all the time.
