- Lot Description
This is one of the notable and visually unique diving helmets ever produced. Made by the Yokohama Company in Japan, this was one of their most popular and expensive helmets ever produced! Used by divers worldwide for extreme deep diving, this helmet is arguably the pinnacle of copper & brass mixed gas diving helmets.
Looking directly at the front of the helmet it is very similar to others made by Yokohama and DESCO during the 1950s and 1960s. With a quick glance around the back, then all the magic appears! Incorporated into the back a compartment housing a canister containing a Co2 absorbent. Various plumbing and fittings are also part of the backside and front of the helmet, giving it an appearance, unlike any other helmet.
This helmet undoubtedly was used in numerous extreme deep diving jobs. Due to their original expense, hazardous environments it operated in, and diver safety, these helmets were generally always well maintained and taken care of.
The helmet does have a series of numbers on both next rings, which do match. The original Yokohama brass ID plate is still intact. The front brails or straps also have Yokohama Diving Apparatus Co Ltd cast into them. All 12 wing nuts, four brails, four brail shims, three windows, internal tubing, internal communications, valves, and spring-loaded safety latch are all present!
This helmets exotic appearance, completeness and fantastic patina make it one of the most popular helmets for collectors. Its original expense, limited production, functionality, and worldwide use have also made them highly sought-after treasures. This example is certainly worthy of any museum or private collection!
All diving helmets in this auction will be accompanied by a certificate of authenticity from Nations Attic. 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. The display stand shown in the photos is not included. The option to purchase one after the auction will be provided.
All items will be shipped with a signature required upon delivery and full insurance either via FedEx or the USPS Priority Mail. Worldwide shipping is available; however, no ocean freight will be offered on large items. DHL Express is an option for international shipments under 600 pounds via air.
