It had its own carrier that I assume was screwed to the mounting plates on top if the WS19 case. The set and supply unit/LF Amplifier lay on this (side by side) and were secured by webbing straps.

I've never seen the carrier, but there's a drawing (unfortunately oblique) of one in one of the manuals.

The supply unit was only ever 12V input, and for 24V 2-wire systems there was a WS19 power lead that looks like the one for the British WS19HP, but supplies 12V tapped off the dynamotor inputs (requires Canadian Supply Unit No.2 or possibly the Eicor one).

Aerial feeder is about 18" of P11 with a split plug on one end for the set and a ring terminal for the base.

Aerial Base No.8 tended to be used, with 8-ft (2 sections) of 'F' rods.

You can't use a WS19 power "dogbone" between set and PSU/Amp because not all of the pins are connected.

If you remove the WS38AFV you have to insert a blanking plug (well, 6-pin socket) into the C.U.16 to restore the tank intercom (I think) circuitry.
