The late Ray Sturtivant…
Having done a little research before posting my last post, I did include on a reply that disappeared before I could send it that there was a lovely picture of two Spits from 759NAS escorting an (unidentified) Fw190 in FAA A/C 1939-1945 (page 380 in my copy). The far Spitfire is R7193 Y1M, and the closest is…L1096, Y2W.
And (seeing as Derbyhaven left out a tiny bit of info in the above reply) it came to the Fleet Air Arm as a mark Va.
