Found the break. It's in the cable below the microphone. Now for some rework. Thanks to all who responded.

I used a drop of de-oxit on the contacts. Blew them dry and still nothing. I checked the microphone plug and the connections are sound there. I tried an Astatic D-104 that I wired to work with it and it keys but the mic element is bad and I knew that. I really want to use the MM-1 but am at my wits end.
