SOVIET RUSSIAN AIRCREW OXYGEN MASK TYPE KM-34d

KM-34 and KM-34D (ZSh-5) This pressure-demand type mask was designed specifically for the then-new ZSh-5 helmet and is essentially just a distinctly modified KM-32 rubber inner facepiece with an outer KM-34 type fiberglass shell. Mask is attached to the (ZSh-5) helmet with bayonets and as such cannot be used with earlier made ZSh-3 or any of the leather helmets (unless the attachment fasteners are changed out). As with previously made KM-30 and KM-32, this mask has the attachment for the occipital bladder (which was secured inside the ZSh-5 helmet’s aft liner). KM-34D does not have a built-in microphone; pilots relied on the La-3 and La-5 neck mounted microphones, although a mic kit can be added to mask, if desired.
A very rare soviet russian oxygen mask it was a short lived mask being supassed by the Km-34d (2) very early on in it production.
