[Milsurplus] CW-29173 switching relay NOS p/o ZB-2/3 carrier homing system for trade

[Jack Sullivan]

I have an extra one of these components of the ZB-2/3 aircraft carrier homing system developed prior to Pearl Harbor & used throughout WW2. This includes the mounting plate. It is identical with the RE-1/ARR-1 except for some minor circuit changes. Will trade for manual copies of ZB/YE/YG system components.
