Early T-17 Microphone USAAF - Signal Corps

1st pattern Signal Corps T17 microphone with cord and plug, mint overall condition. Early made 1942

On board of USAAF planes:

             a. The T-17 utilized as a Cockpit Hammer came in handy to break loose a window latch after landing or to loosen a stuck "Eyeball Vent" at altitude. During flight a quick bang with the T-17 on the panel of that hydraulic A-3 autopilot will often cure a sticky servo.

             b. Cockpit Signaling Device. Often used on long over water flights when crew members are not on innerphone. Hold the mic and bang the side of the control column.    3 bangs means don your headset.     Repeated banging means Wake Up.

              c. Handy "Extend Your Reach Gadget." Often using the hang up hook to to flip toggle switches on the overhead panel when they just out of reach and you do not want to remove seat belt. On certain aircraft be careful of the feather toggles.
