A couple of Bristow Whirlers have cropped-up on pages past including this one from page

And this one from page
34 (the same page where you are posing in front of the 'Jabberwock'):
A Bristow 'Whirler' (behind Douglas Bunn's 206) in Alan's Shoppe at 'Redders'
Re: the 'leg folding' photo, yes slightly effeminate (as you say) and doubtless designed to accentuate their fearless leader Richard Hadlow, lol! (Did you observe how the chaps on the right all have their legs folded one way and those on the left another - grief!).
Regarding the Sergeant pilot offering his 'victory salute', sadly all I have is 'Fred A' - perhaps someone may come along providing confirmation of his surname but it would need to be a Fred who served with the RAF in Asia in the mid-to-late 60's.
A couple more Whirlers (RAF) to be posted (maybe later today).
