This mask was manufactured by The Ohio Chemical & Mfg Co. in October 1944.
This mask is fitted with a rare T-44 microphone assembly. This comprises a deep chocolate colored loom (CO-287) with an American version of the standard RAF bell jackplug to one end and a Type T-44-A magnetic microphone and AAF JK-26 socket at the other.
The T-44 fits inside the nose section of the mask alleviating the need for a throat microphone. Used primarily in aircraft fitted with RAF radio equipment, this loom enabled AAF crews with the 8th and 9th AAF to plug their American made headgear into RAF aircraft.
The standard AAF helmet jack plug connecting to the JK-26 and the bell plug to the aircraft.
