Hey FFM,
It looks like a prototype helmet made for the movie "The Sphere"
Kirby Morgan manufactured a few for the film, if you look close near the rear of the helmet you will see a small KMDSI diamond and the headcushion is a typical KM unit.
The units were desinged to show the actors faces not for function or efficiency, they did use a fold up oral nasal mask internally to try and decrease the build up of CO2 but as you already stated this was a big problem with all the dead space in the helmet.

Morse shallow water (warning, no sexy lady in photo!!)
My Edit - This is in response to your second photo FFM, do you have the information on the first mask. I do not recognize it...
