Many thanks, John. That is certainly a very interesting image of the TT installation on a Westland Wapiti. I wholeheartedly agree regarding the lack of definitive information on these early TT installations and the paucity of information in Don Evans "The Long Drag". There must be information out there somewhere; as they say in the classics "it is just a matter of finding it". The quest continues.
As an aside, do we know what the significance is of the swastikas on the surfaces of the lower wings? I appreciate that they are not German related per se but would be interested to know what the symbols represent ...
Thank you again for your response.
