Starting in 1968 DESCO (Diving Equipment and Supply Company) debuted the now iconic and still in use Air Hat. These helmets are also known as Free Flow or Pot Hats. Constructed of spun copper with a large acrylic window, this model is one of the most widely used helmets in the world.

This helmet is serial #413 with two patent stamps present. The helmet is also stamped on the top window frame POWELL BROS 900. It’s likely this helmet was used by the Powell Brothers River Divers. After years of use, the helmet shows exhibits the original spun copper body. There are a few minor dents, but none are severe. There is no neck dam present with this helmet.

All diving helmets in this auction will be accompanied by a certificate of authenticity from Nations Attic. The certificate will have a unique number that will match the number on a tamperproof hologram decal placed inside the helmet.
