Miller Dunn was based in Miami, Florida. The company was known for making shallow water helmets during the first half of the 20th Century. Their first helmet was simply called the Divinhood. This shallow water helmet is relatively simple in construction with one round window in the front. Miller Dunn would improve upon this model with the Divinhood Style 2 helmet. Also a shallow water model, this helmet used two angled pieces of glass on the front. The peak of production would be the Divinhood Style 3. These were made in large numbers during World War 2 for the US Navy. Also during World War 2 Miller Dunn made the US Navy Mark V helmet. The Mark V is a deep water helmet and was the only deep water model Miller Dunn made. Miller Dunn also produced a small air pump in larger numbers as well. The helmets would come in a wood crate with the helmet, air pump and hose for a complete diving kit. If you have a helmet that was made by Miller Dunn, please let us know, you might  be surprised just how much we can pay!


Dunn Divinhood

The Dunn Divinhood was the first helmet Miller Dunn manufactured. Many people refer to these first helmets as style 1. Rather than a tag or ID plate, these were simply stamped into the side of the helmet. They say Dunn Divinhood; U.S. Pat. Aug. 1916; Foreign Pats Pending; Miller-Dunn Co. Miami, FL.
