Thanks for that. I'm doing my aviation law at the minute so I should really have gone straight to the LASOR'S. It'll definately give me a good start anyway. I think I probably will end up ringing the CAA for some guidance, or discussing it with certain members of my flying school (one of whom is building a gorgeous mustang/hurricane type mix-up completely from scratch!). He's hard to get hold of though, hence why I asked here.
I know my question was vague, but I was only looking for a point in the right direction. Pljus I'm sure there must be a few civvy warbird pilots on here who will be able to help.
Thanks again FlyBoy.
