Nation's Attic 2024 Diving Into History
Lot 113:
This is one of the most classic yet rarely seen diving helmet models in the world! This is a Danish 2 bolt helmet invented by Peter Hansen over 100 years ago. Hansen came up with this design to enable divers to get in and out of their suits and helmets quickly while working in extremely cold temperatures. The rubber collar on suits would get very stiff when frozen, making a 12 bolt pattern suit a huge hassle! Various countries militaries, including the Danish Royal Navy, and countless commercial divers used this iconic helmet.
This four light configuration features a threaded faceplate which threads on and off with ease and an old gasket is intact. The helmets serial number is 519 with a crown stamp, which is present on both the helmet body and removable brass ring. All of the glass is present, plus the brass guards. There are no major dents or damage visible on the copper body. The two bolts on the breastplate are steel, so possibly replacements. The air fitting has a barbed hose fitting attached. The copper body and brass hardware have a very nice patina, giving this helmet a majestic appearance. Danish 2 bolt helmets do not enter the market often! A wonderful example with lots of character like this is a special find!
