подводник (Eng-Podvodnik or Submariner) ABM-1M Soviet Double Hose

[Vancetp]

I just bought some stuff from the Ukraine. I got 2 Soviet non-return valves from him. They are strange looking things, and I'll post some info about them when I get them.

Here's what they look like. They are integral to the mouthpiece hose connector, or I'm just getting some extras. These will only be for one side. What's your guess? Intake or exhaust?

A simple mushroom valve would seem to be much easier to make, and I will for the other side...
