Miniature U.S. Navy Mark V Diving Helmet

A handcrafted miniature U.S. Navy Mark V diving helmet measures approximately 6 x 6.5 x 8 inches and is built from aluminum with a copper and brass finish. Weighing about 1.5 kg. Designed as a decorative collectible, it pays tribute to the original Mark V deep-sea helmets used by the U.S. Navy throughout much of the 20th century. The Mark V design, first introduced in 1916, became an icon of maritime exploration and salvage operations.
