Thats neat. In Cody Wyoming, theres the Winchester Museum which is a similar thing for antiques.
Been there. Seen that. The highlight for me was seeing an actual Gatling gun, which they had on display. I didn't see it fired, but from what I understand, it was fully operational. And for those who might want to see one, here is a partial list of films, TV movies, and TV shows in which the Gatling plays a part.
Four feathers (2002)
The Gatling gun
Intolerance
The Lone ranger (2013)
The New maverick
The Northwest mounted police
Only the valiant
Outlaws is coming
Rooster Cogburn
Shanghai knights
Sherlock holmes: game of shadows
Siege at red river
Tremors 4
Van helsing
Vera cruz
The War wagon
The Wild, wild west (1999)
The Wild, wild west (TV)
Young blades
Gatling is dead. Let it R.I.P.!
