They wouldn't let me pick it up for display, so I had to take a not-very-good shot of it through glass at the NRA convention. It's purported to be the revolver (or one of the revolvers) used by Clint Eastwood in the movie Dirty Harry.

I still cringe when I watch that scene in Dirty Harry at the cross in the park. Scorpio makes Harry pull his gun out and toss it down, you can hear it hit the concrete. AAAGGGHHH!

Racegunner,
Like you, I'm somewhat skeptical on this one, but just reporting what was placarded. It's a 6.5" barrel, not a 6" as indicated.
Also, it's pretty beat up. It may be that it was used as a prop gun for dropping, hardscrabble scenes, etc. That would be my best guess.
That whole scene with Scorpio in the ski mask, "ooh, that's a big one!" sort of weirds me out.
