Opssys - Yes, that's about right. But you also have to consider the engines, as they are separate entities with their own data plates and logbooks. If your desired wonderplane uses an engine which is generally available, e.g. Merlin, R-2800, Allison, R-1830, then you can go and buy them. If it needs a pair of Vultures or a Napier Sabre then you are going to find it a lot harder.
Pop., Treaders, I've been told that the tailplane spar on ACDC is original. I imagine that's all, apart from the data plate, of course.
