What is this weird thing?

[hbru123]

This was found at a WW2 Military training base where I have found rations and land mine pieces, the black pieces in the middle I am pretty sure is old rubber, there is also a red band that is rubber on the outside. I have no idea what it is.

Thanks!

Looks like it could be a seal of some kind?
But to what?

It's a Tub Stopper or Sink drain stopper

Gas mask diaphragm perhaps? Does the rubber boot look like it may have allowed air one way but not the other?

Ya that's definitely what It looks like.

Ya. I never thought of that.

Definitely! I never thought of that. I don't see holes that go through and it has a metal back so I don't think air could go through. But you never know!

Looks like an old cone speaker

One way check valve, maybe to a gas mask.

If the center is threaded it would look like the piston from an old pitcher style hand water pump. That would explain the rubber on the side and bottom.

I say it’s a burner from a Coleman or camp stove....

.... I like sink stopper.....just can't imagine an iron piece on my gas mask.

I agree. I would think a gas mask would be a lot lighter maybe made out of aluminum.

Thanks!

Only other thing is about a 1960s GM gas cap , while missing the outer cover lock ring.
My 63 vw gas caps pretty close, they all use a outer 3 tab twist cover rubber vent
and rubber/cork seal inside

some sort of valve damper
maybe a back valve preventer
