Congrats on the award Hairy!
You want to watch making suggestions like that Damien, those darstadly Auster pilots sometimes camoflague theirs too, and I suspect aren't above taking a leaf out of the Grasshopper pilots' book and tying bazookers on to handy things like struts!
Then again there's a faint connection between Austers and Little Nellie! Yes, I was watching You Only Live Twice last night when I should have been PPRuNeing! And the Dambusters the night before (thanks Chris!).
