IMHO, the ULTIMATE Deep Sea Diver ever. Produced by Hot Toys in 2007, this figure comes with die-cast parts (Copper helmet, mesh cutter, regulator, rebreather, copper bottomed boots) and a leather dive/pressure suit with chain-mail gloves. He also has a pressure activated submersible bomb.
Fully decked out and ready to dive
Love the headsculpt too! Check out the copper helmet.
