Jon, I have scanned the M201 amendment doc plus the M201 circuit with the original thick film pcb and PA circuit, plus interconnections.
Just emailed it to you.

Available for anyone else if they message me with your email address.

From this, it would be possible to make a modulator with compression along the lines of that in the M201, using discrete components
.
I also found the sheet with circuit, components and connections for am and fm use of the "ladyshave" microphone. This was discussed in another thread, but don't know which one.
It is included in the pdf above.
I will attach as an image now, not sure how it will display on the forum though?
