Now that I got the heavy post out of the way for today, I can concentrate on the important stuff like guns in anime.  Snagged this selection from Samurai Deeper Kyo.  It was the only one I could find of this interesting weapon.  A three-barrel pepperbox design, single action.  When the hammer is cocked, the entire barrel assembly rotates.  Muzzle-loader, obviously.  Looks bigger than .50 caliber.

Anyhow, I also GIMPed the finger, but I'm not as good at that as some people.
