Bill pointed you in the right direction ---
It is basically a pre-amp board with a 9 volt battery and wiring to PTT switch, microphone element and cable to radio. The schematic is self-explanatory. I wouldn't trust a photo of the microphones today, unless it was a rare one sealed in the box.
I don't need the plug wiring, just an internal pictorial so I can figure out what goes where.
Surplus Sales of Nebraska had those last ones (sold out in late 1990s)
