Item Overview

Description:

General Aquadyne DMC-7 Vintage Fiberglass Diving Helmet

This is a classic fiberglass helmet made by General Aquadyne who were based in Santa Barbara, CA. This is a model DMC-7 which first came out in the mid-1970s. This example features fantastic-looking burgundy paint with all its original hardware. There are a few small handling marks in the paint; otherwise, it is extremely nice. These seldom appear on the market in this impressive visual condition!

The certificate will have a unique number that will match the number on a tamperproof hologram decal placed inside the helmet. This information will be kept on permanent file at Nations Attic and help ensure the provenance of the helmet and authenticity.
