The National Museum of the US Air Force in Dayton, OH also has a B53 casing at the entrance of their Cold War exhibit. I think the sign for it just says rather bluntly "B53 Thermonuclear Bomb", which I always found kind of funny in a dark Dr-Strangelove-esque kind of way. https://www.nationalmuseum.af.mil/Visit/Museum-Exhibits/Fact-Sheets/Display/Article/195680/b53-thermonuclear-bomb/ https://www.nationalmuseum.af.mil/Visit/Museum-Exhibits/Fact... Edit: The one right near the entrance is actually a B41. The B53 is somewhere else in the exhibit (apparently they have multiple H-bomb casings).
