Unusual find - Aluminum Constant Flow Mask

Fri May 19, 2017 10:09 pm

A friend at my LDS brought this in. Looks to be of good quality, but probably not from a diving supply manufacturer. There is a nipple on the top to attach an air hose,and a capped nipple in the front below the glass faceplate is where the excess air can be released.

Here's the front view:

Here's from the back, [rubber seal is still very supple]

Also of interest, and visible in the front picture is a US Divers Audio Reserve Valve [pg. 5 1963 catalogue] seems to be complete with the interior audio mechanism intact. Pretty cool stuff that you don't see every day.
Too DAAM Many double hoses, It's not a hobby, it's an addiction.

Really cool find. A Navy buddy of mine said he used something like that to inspect ships hulls.

Doing it right should include some common sense, not just blindly following specs and instructions. .Gary D, AWAP on SB
