Your drawing appears to be a Mk3 in which case the mast on the sponson would just be visible.
The reference photograph does have a mast visible on the port sponson. Thank you for clarifying that; and if the fleet mostly consisted of Mk3, I shall leave it that way. I appreciate the responses guys, thank you. The other thread did not answer all of my questions; and if I am honest, I never expected anyone to have previously asked the question. One final question if I may:- I have seen some aircraft with a (fibreglass?) protrusion below aft of the cabin door. Looks about a foot square and a few inches deep. My reference photo appears not to have this - is this a legacy item from previous models?
