The middle ship is a Piranha, it is a prize ship and was only available by participating and in some cases winning games at conventions that were run by or sanctioned by ICE. I was in the Ottawa at the right time so I participated lots, but never one the bigger prize ships. That is my last one, I also have the Dolphin and Battle Axe in my collection. The other's are Tealhawks they came in the Deluxe Edition and mine are plastic, you can get metal ones.
They painted up pretty easy, I made sure they were bright yellow, cause I never paint that color much. So haven't painted much since then, going to have to bust my ass to have a new week three entry... ;-)
