DESCO general information.

Received from:
Ric Koellner
President
DESCO Corp.  

Mr. Bech,

Unfortunately our information on the rebreathers we manufactured is incomplete. 

I can tell you DESCO was contracted during WWII to produce rebreathers for the
U. S. Office of Strategic Services (forerunner of the CIA) and the first production run went to them.  

The U.S. Navy also purchased them during the war.  

After the war DESCO adapted the B-Lung to commercial use and marketed them.  A simpler A-Lung was developed for sport diving. When the dangers of oxygen poisoning became apparent in the early 50's DESCO discontinued production of rebreathers. 

In the book "Mask and Flippers The Story of Skin Diving (Publisher: Chilton Company 1960)", written by Lloyd Bridges (the actor from Sea Hunt) and Bill Barada, the rebreather is covered and its falling from favor due to the poisoning problem is mentioned.   

I have included photos from our files.  

The A-Lung is the unit with the bag in front and the single hose mouthpiece.  

The B-Lung was a double hose unit with a face mask. The early B-Lung used the oval mask with the nose bumpout. Later B-Lungs used the Jack Browne Mask adapted to accept the rebreather hoses. Coincidentally a early B-Lung was offered for sale on ebay and misidentified as a Momsen Submarine Escape Lung.  

DESCO also offered a C-Lung unit which was a rebreather mounted to the DESCO Lightweight Suit to make a self contained unit (see photos). 

 Over the course of years and several moves to new buildings sales records were lost or discarded. The reason we know about the OSS contract is a few years ago a CIA historian contacted us for information. I hope you find this information useful.

Best regards,

Ric Koellner
President
DESCO Corp.
