This is one of the first decompression/recompression chambers ever developed, fabricated some time in the early 1960's and used at least once to save the life of a diver experiencing a case of the bends. The unit has not been pressurized and does not feature a compressor. It was acquired by me in an estate sale and I would like to find it a new home, preferably in a collection or museum. I will be taking offers until April 30th, after which the highest offer will win the bid. Please do not bother bidding/making an offer less than four figures.Shipping/delivery can be arranged for an additional fee to anywhere in the continental USA.
