RE: Rebuild or Replica??

I asked myself the very same question a month or so ago.
Either Flypast or Aeroplane had an article about a P40 that had been “restored” in the States to better than new condition.
They seemed very proud of everything they had replaced to achieve perfection.
It sounded like there were only a couple of fuselage frames that weren’t brand new.

If there’s too many bits left over we could end up with the same problem they have in the classic car world. For example, there are two Jaguar D-types with the same chassis number. It (they?) was originally crashed in the 50’s and fitted with a new front subframe, which carries the chassis number. 30 years later, the original subframe was found, straightened out, and fitted with a new back end.
Which is the original?
