Fresh additions just hit our website!

We've recently added several classic diving books and two rare WWII Vince U.S. Navy diving knives to our inventory. We've also significantly reduced the price on this outstanding 1944 Miller-Dunn Mark V diving helmet.

The Miller-Dunn helmet is now priced to sell, and we fully expect it to find a new home soon. If you've been considering adding an exceptional WWII-era diving helmet, a scarce Vince dive knife, or other historic diving treasures to your collection, now is the time to act before they're gone.

⚓ Just Listed | Available for Immediate Purchase

If you've been waiting for something truly different, this may be the helmet.

Now available on OldHelmet.com is an extraordinary antique diving helmet featuring an exceptionally rare four-bolt configuration, a style seldom encountered even in advanced collections. Professionally polished to a brilliant mirror-like finish, this helmet has an incredible presence that makes it a standout display piece.

Rather than being represented as an original factory-built helmet from a single manufacturer, it has been carefully assembled from authentic period components, resulting in a remarkable and visually impressive piece of diving history.

Many of the finest helmets we offer are purchased within hours or days of being listed, so if this one catches your eye, don't wait.

Two exceptional pieces from our record-setting 2026 Diving Into History Auction are unexpectedly available once again.

Unfortunately, an international bidder failed to complete the purchase of these remarkable John Date pieces. While disappointing for both us and our consignor, it now presents a rare opportunity for another collector.

🔹 Rare John Date Matching Number Diving Helmet (Lot #118)
🔹 Rare John Date Diving Knife (Lot #119)

Both items are now available for immediate purchase at prices below their total auction cost, including buyer's premium, with professional packing, insurance, and shipping included within the contiguous United States.

Documented John Date equipment is among the most desirable and difficult-to-find pieces in commercial diving history. Opportunities like this are exceptionally uncommon, and once these items are sold, we do not expect another chance anytime soon.
