Are you really sure there is no 33 Sqn Association or is it just that they are perhaps not 'alongside' the active squadron as they could be?
A good friend, who flew Hornets on 33 in Malaya and was then a big cheese when the squadron reformed with Puma, has reported several occasions in recent years when he has been to a reunion bash.
I will email him this morning and report back!
Good luck with the new body, however. I'm sure a trawl of those ex-33 bods who attended 'Puma 40' at Benson would probably know if I am mistaken.
