Sorry I can’t help further. If I was to take a guess maybe 1960 = something to do with Malaya as the RAF operation ended that year and 1973 being Yom Kippur year possibly he was based at Akrotiri. As I say totally guessing and may lead to a wild goose chase.
Good luck in your quest.

Thanks for the suggestions Mothminor, I do fear that I am heading towards a brick wall.

Thanks again:)
