Miller-Dunn style 2 Divinhood Shallow Water Diving Helmet

In the collecting community, regarded as the most desirable shallow-water helmet by the manufacturer Miller-Dunn, this stunning example is as good as it gets. Featuring large, angled glass ports for excellent visibility, it became the US Navy standard. It popularized marine biology and underwater photography through scientists such as Dr. William Beebe. However, its unique look often distorted straight-ahead vision, making early models rare and highly sought after by collectors.
