Used in the Seventies in the Naval Aviation, it doesn't have amicrophone and a  adjustment of volume. The antenna is flexible and is rolled up in the plastic handle. The powering starts as soon as one withdraws the known fixed pin there handle.  The power supply is separate.
It is not used any more today.
