If you are ever way out West and want to see one of the greatest collection of firearms in the world, this is the place. The Buffalo Bill Center of the West in Cody Wyoming.
The Cody Firearms Museum, within the Buffalo Bill Center, contains a huge collection of firearms covering 500 years worth of their history. It includes separate collections on Military firearms, early Black powder guns including Wheel locks, Flint locks, etc. and, of course, the Guns that won the West. It is a must see for any true gun nuts;-) Even if your like me and it takes decades to get there it is worth it.

Enjoy and stay safe
