I have a few WEA oxygen mask receiver brackets. The WEA (Wasser Entreglung Aktiefierungs Einheit) is a water activated opening device. This device contains a tablet that solves in water and that activates a spring to push the bayonet from the retainer.
It only opens a little, just enough to prevent the pilot from drowning. When the mask would be still on the pilot's face, there is a chance of breathing water thru the oxygen hose. For the Military or Aviation collector.
