We had mics like that in the control tower at SLC when I started training as an airport traffic controller with the Civil Aeronautics Administration in 1950.

I am in the process of re-purposing a very old microphone as you can see in they lower picture, FEB 1944.  A new microphone cable should be here next week.   The carbon element inside was bad so I went for a MAX9812 Microphone on a board for $1.75 on eBay.  This microphone was not from a telephone.  Any guesses?
