The classic Tau Devilfish APC from the displayt cabinets at Warhammer World.
Always quite liked the Tau concept, but was never sure how well it fitted into the Warhammer 40,000 mythos. They seemed a little too high tech for the universe background.
Anyhow the Devilfish is a nice looking model and this is how it looked when the Tau were first released all those years ago.
