I would recommend a Smith & Wesson Model 1917 revolver for a couple reasons. I have one of the Brazilian contract S & W 1917 revolvers that were made in the 1930's. Colt does not have a similar model, and from what I've heard, the steel was better in the 1930's as opposed to before WWI. Also, there is an aftermarket adjustable rear sight called the FDL Wondersight that can be added to the Smith & Wesson without modification to the gun, but requires drilling and tapping a hole on a Colt, which would not be good for collector value. Plus the Brazilian crest on the S & W is kind of neat.
