Michel, Excellent work!
Maurice/David Herbert,
The extra aerial base on the right rear of the turret is for a WS38 Plan “A” installation which used a standard WS38 (not WS38 AFV).
Installation drawings can be found here (very poor quality images):

I agree that an aerial base located by the co-driver should indicate a hull mounted set ( but what type of set?). I am surprised by the presence of the hull mounted aerial base on AVALON as space on the right sponson was already restricted in the Crab.
