Dr. John Smith,
Thank you very much for both the information and the links – which I have found very helpful.
I am researching the flying career of John Charles Atkinson, focusing on the Channel Dash operation. As you mention he was awarded the DFM for this event and I would have liked to have found a picture of the Manchester he flew that day. However, from what you say it would seem unlikely that any are known to exist.
Again, many thanks for all your efforts to help me.
Kind regards, Malcolm.
