Dora 9 - my signature is illegible. I'll send you a copy when I get back to HK. I'll also send you the scans of my logbooks from that period so you can match them if you ever get bored enough. The RAF engineering system used to keep samples of our signatures because of our signatures because of people like me.
The state of 478 sounds like a nightmare. She was the quickest in the fleet at EFTS, but if all you have of her is the fuselage, I can understand why she isn't as quick now. The rigging is everything on the Chippy and the expertise of the engineers at Swinderby got her perfect for the air racing. Her engine was one of the best too.
