WWII U.S. Radar Indicator ID-6B/APN-4 – Aircraft Radar Display Unit

Original WWII-era radar indicator unit ID-6B/APN-4, dated 1944. Features circular CRT display, full control panel with labeled adjustments (gain, sweep speed, delay, station, etc.), and original connectors. Good overall condition with typical age wear and some clouding to the screen. Untested. Impressive early airborne radar display—excellent centerpiece for a serious WWII electronics collection.
