As for that lost-in-the-mud Spitfire 'recovered' in Oz, if it's anything like the similar one, found under the beach at Calais as a rotted out hulk, it'll be restored to mint flying condition in a couple of years too.
I guess if they use a single part of the original, no matter how heavily they have to refurb it they call it original. Wish we could get away with that.
