Recognition Light Control Front Panel, IFF, WW2 P-47 Thunderbolt B-29 They came to us fromThis front panel of the Recognition Light Control Assembly appeared in nearly all of US Army Air Force aircraft of WWII by the end of the war, including the P 47N Thunderbolt Fighter (see photo of the right side panel of the cockpit indicating the location of the switch box).
