Ok, how does it work?

No mouthpiece .... Just asking; because, I've never saw one of these before. Even the first stage looks different than anything I've saw.

Who made it?

Any one got a parts breakdown for it? (otherwise, I might have to buy it and break it down to see what's inside; I'm a very curious critter).

This one looks interesting, also.

I gotta quit looking at e-bait ... I'll go broke!

Robert, check out Pg's 136-143 of Basic Scuba... it's a tilt-valve!

I noticed it said the mouthpiece was missing .... looks like a predecessor to the USD Aquamatic II ....

I'm wondering if a Nemrod Delta mouthpiece would work on it; those are rectangular too!
