Sort of a shame the WW2 400 Hz selsyns are no longer "inexpensive" although a PM magnet, an Arduino flux compass, and some hot glue will probably replace a selsyn and all the analog hardware to remotely read out azimuth position in degrees.
I've agonised over azimuth sensing - been looking for a battery-powered device with built-in Wi-Fi or Bluetooth sender and a PC Windows receiver that "exposes" the azimuth value for easy capture by a simple program (e.g. data logger).

Some years ago I tried a device from (via Amazon) with a display program that tries to mimic an aircraft attitude indicator. It was disorientating and made me tear my hair out. And anyway this did not let me capture the azimuth value.
