Oops, apologies for posting and not answering...
Airbedane - I've not come across the RAF guide, although I know someone who might be able to get hold of it. If not, I'd very much appreciate a photocopy; I'll let you know.
BeauMan - Thank you very much for the kind words! I know I'm priviledged to be able to fly the Chipmunk, and if I can share some of that through writing it all down here, then I'm glad. Just be greatful I'm not able to waffle on in person.
BletchleyTugie - I went to sixth form college there! Affirm, a proper Chippie with a Gypsy Major engine. Absolutely no idea whether it went to Belgium recently. I know 'John' has no aversion to flying it abroad, but whether he has done in the recent past... sorry, not a clue.
Pilotwolf - Why do I suddenly have the urge to buy shares in outside toilets? Although I'm also rather biased.
Tim Inder - Yes, it's an aerobatics competition... but not as you know it. And it's in a Cap10b. So a tailwheel conversion will prove fairly handy.
Paulo - You know full well my surname isn't either of those. Nor is it Underpants. Despite the rumours.
