This reg is not for sale, but my buddy just got it for a lot more then I could pay. It was posted on one of the sport diving boards.
Just goes to show what can come up every now and then.
The post was:
"I have just uncovered a 1950's US Divers Aqua-Lung 2 hose regulator with blue hoses in brand new condition. The box was sealed from the factory with US Divers tape and just cut open yesterday to view the contents. I found this tucked away in a dresser drawer in my late fathers ham radio shack. I know that this drawer had not been open in at least 40 years and the box, literature, and regulator are in n NEW condition, an unbelievable find. Serial #20837 Cousteau-Gagnan process. I have not dove in about 20 yrs and do not have a use for this so my search led me to this site to see if it has any value. "
