Union Civil War re-enactors from New York fire two-gun salutes with a Parrot rifle at the 90th anniversary celebration of Fort Dix, New Jersey, July 18.

Of course, a gun like that would look good snuggled between the Castle flagpoles...

Hi-res available here. If you want the original (about twice the size of the higher-res one) drop me an email.
