This piece of diving armor is referred to as Hagenuk or Iron Duke. It was made by Hagenuk in Kiel, Germany. In 1931 Iron Duke dove down to 450 feet to salvage sunken treasure from the wreck of the Egypt. The diver recovered 10 tons of silver and 5 tons of gold. It was the greatest treasure salvage of all time.
