Sony ECM-99 One Point Stereo Electret Condenser Microphone.
I bought this microphone in the 70’s and used it a couple of times with my Revox A77 tape and it gave a distinctive clean crisp reproduction for speech. Since then it has been stored with battery removed and comes with original box, instructions and stand clip. All are in mint condition with no marks, scratches, dents or wear - in fact, as new.
