KM-32 NBC Oxygen Mask

This is yet another version of the KM-32 mask. It was made for pilots operating in areas affected by nuclear and/or biological weapons. This mask covers pilot's face. Bottom part is the actual mask, which somewhat resembles KM-32 design; while upper part is made out clear plastic with rubber edging. KM-32 NBC mask has one oxygen hose that connects to the plane's oxygen system. Exhale (at least that what it looks like) system is located right under the oxygen hose. Inside of the mask, right near the plastic glass, there are two ventilation points - these were made to keep plastic from fogging up (there is no electrical heating system like the one in GSh series of helmets). KM-32 NBC also has a sealed microphone. Mask is worn either over the pilot's head or over the leather helmet.

Yet another box that came with the mask. It's made out of the black plastic. There is some nomenclature on top of the box.

On the bottom of the picture is the oxygen hose. Just above it, under the clear plastic, there are two ventilation points, which should keep plastic from fogging.
