Looking for Reference - Inside of an Oxygen Mask

foreverendering

Does anyone know what these things look like on the inside? I've found countless shots of gas masks & oxygen masks (like the style a pilot wears), but my meager googling skills have been unable to turn up any reference of the inside part of the mask. I haven't got a clue what its supposed to look like in there.

Any suggestions on where I can find shots of the inside? Or does anyone happen to have an image saved to their hard drive they could post up?

Thanks for the help

Try flickr or global security...remember seeing accessories like that on there

Awesome - I found some workable reference on flickr.

Thanks!
