Intercooler Flap Position Indicator, Boeing B-50 Superfortress Bomber, Type DJ-28

$24.50

This is a dual engine Intercooler Flap Position Indicator as appeared on the US Air Force's Korean War-era Boeing B-50 Superfortress, a more powerful-engine revision of the iconic WWII B-29 bomber Measures. Two of these indicators appeared on the B-50's engineer's instrument panel (see photo), each indicating the intercooler flap position on engines 1 & 2 or 3 & 4. By toggling the momentary-contact intercooler switches, the flight engineer controlled the degree to which each engine's intercooler flaps were open and thus managed the carburetor air temperature.  Made by General Electric, type DJ-28, model 8DJ28AAN.  Meausures 3.25in diameter and ~2in deep. 

It is in excellent condition given its age.  The dial markings are clear and the glass and case are intact. See photos.  It has "B-50" stamped on the rear case.
