Item Overview

Description:

1915 Miller Dunn Divinhood Style 1 Miami, FL Diving Helmet

This rare helmet is an early example of the Divinhood, an innovative diving helmet produced by the Miller Dunn Company of Miami, Florida. Made around 1916, this helmet is a foundational piece in the history of American shallow-water diving and is the direct ancestor of all subsequent shallow-water helmets.


The Miller Dunn Company began producing the Divinhood in 1915 and continued until 1924. The Divinhood revolutionized shallow-water work, making it easier for divers to perform tasks like research and underwater photography. Its simple, yet brilliant, design is still admired today. The body is made of copper, with a brass handle, air-fitting elbow, and a circular window frame. An extra copper band on the front and back allowed for lead weights to be attached and secured with brass hardware.


This wonderful original example features an unmistakable original green, brown and dark red patina that only comes from use and 100+ years. During the first year of production, Miller Dunn did not stamp these helmets. We have not been able to identify a stamp, but the surface patina may be preventing its appearance. The copper body is free of any notable dents. The glass is intact with no cracks. The air fitting and brass handle are in good condition. The four lead weights feature a shallow company stamp on each. There is no hardware securing them to the helmet.


Overall, this is one of the nicest original Miller Dunn Divinhood Style 1 helmets we have ever handled. Its overall condition and visual appeal make it a special example!


All diving helmets in this auction will be accompanied by a certificate of authenticity from Nations Attic.
