My company just bought a fish tank for the production office. I picked up the Lindberg "SS Gato Fleet Submarine," weathered her, blew a hole in the side, and built an interior out of foil and photo etch.
When I drove into work, the ballast came loose and destroyed the interior. Grrr...
Regardless, here's what's left of her, in all of her "glory."
