Intrigued of Banbury...
Hi Genghis,
Do I know you??
Lots of speculation no doubt on the type - I reckon is the Granger ( I know Grangers son - wot a wag!).
Shuttleworth face similar challenges with their aircraft - my understanding is that the CAA are 'cautiously helpful'.
I'll draw Airbedanes attention to this thread - I am sure his contribution will be very helpful to you.
If it is something really exciting and 'fits' the Shuttleworth profile (whatever that might be??!!) maybe it could live there?
I know of no finer engineers ( I don't actually know you G!!) to look after it and no better place to operate our aviation heritage/ preserve same for our future generations.
Come on....wotisit??
All the best
