Thank-you Both David and Rob.
A most fascinating variant of the CMP to say the least !
So now we know pretty much where the wires run and the batteries stand.
We know pretty much what equipment was carried , including masts, antennae rods .
Blackout switches and curtains , lights, ventilators , windows.
Q. Was there ever a Onan generator version during WW2 ?
Q. Was there another radio than the WS 19 used during WW2 ?
Basic and fundamental questions. Do we have references ?
