When I was at the Smith & Wesson factory, we toured Springfield Armory which is just sort of down the road. The Armory is closed but one building is a museum, and a traveling exhibit of Smith & Wessons was on display. these were special revolvers made up for the 1898 World's Fair, plus some more historical revolvers. I think this is now a permanent display, but not sure where.
There were some of the valuable revolvers in the world on display there, patent models, tool-room on-of-a-kinds, etc. If you ever get a chance to see these, by all means do so.
And, if you get a chance, tour the factory.
