Hello Graham
Sorry I don't have a lightest idea. I thought that easiest possibility would be David Brown's Carrier Fighters (1975) but a quick browse didn't produce a positive result. So Your guess is as good as mine. Could be any book on Spit/Seafire, someone's memoirs, or an article in some aviation magazine, for example in an old Aeroplane Monthly.
Sorry being unable to help
