KM-30 Oxygen Mask

The KM-30 was the first major upgrade after the KM-16.  The KM-30M nomenclature is pretty recognizable on the side of the mask.  This is also the first mask with the occipital bladder attachment.  It looks very similar to the KM-32.  It also has the forehead connector as is found on the KM-32.  The helmet it is attached to below does not have this connector, but does have provision for it.  Look at the ShL/Z-50 page and you'll see a picture of a leather ShZ-50 with the twin strap connectors peculiar to this oxygen mask.

 
   

Purchaser tips:

The KM-30 is rare.  No two ways about it.  If you find one, buy it.  I don't know, maybe $100 if it is completely intact?
