I am grateful to John Stewart who sent this to me. Adrian Daintrey was a great fried of Diana Cooper and produced a portrait of Paddy in Cretan costume. I cannot find an image of that online. If anyone has one please do forward it.
Daintrey’s Wikipedia page.
Patrick Leigh Fermor 
I guess you eventually found Daintrey’s painting of ‘Paddy’ at https://www.spectator.co.uk/2016/10/dashing-for-the-book-a-lifetime-of-letters-from-paddy-leigh-fermor/ but here it is in case you didn’t.
Thanks Ian – we put up something a while back https://patrickleighfermor.org/2016/09/30/dashing-for-the-book-a-lifetime-of-letters-from-paddy-leigh-fermor/
