Joe,
It may be a trick of the light, but that gun appears to have been heavily buffed and reblued with a modern tank blue. Original finish on the S&W 1917 was a dull blue. So if looking for a good one, try for as much original finish as possible. Of course, if you want to "chop and channel" it then get a functional but doggy looking one and have at it. But they are getting salty in good shape and very collectible, so I hate to see a good one "customized".
