Its not great Carson but here is the one I have;
I notice your list includes the Wyvern TF.1 and S.4. There was also a Wyvern TF.2 which flew with a contra prop as well as the T.3.
Well, bugger me if I didn't go and find another one! This is one of those 'official' jobs with the background removed to keep the location secret and was taken before the first flight.
If I might be ever so slightly pedantic Carson its not 'Wyvern 38' but either Westland W.38 or Wyvern T.3. #
