Sure it has been discussed before. I am sure there is equivalent ideas/agreements with classic cars.

Original - hardly unaltered since manufacture?
(Black 6 would just about be in this section as well as museum examples).

Restoration - substantially complete to start with (would you say a % or center section area?). I would say Fw190A5 is a restoration - nearly all structure/skinning/undercarriage/wheels/canopy etc were reused or original second hand. They replaced two external skins. Main spar rebuilt. Wings - one casting and two ribs replaced though these might have been refitted after repairs and restoration was taken over by Paul Allen.

Rebuild - substantial airframe to start with. Large proportion reused.
3579 - the wing structure was original, large castings were reused, fuselage was new though.

New build - manufactured to original blueprints.(Flugwerk Fw190 or US Me262's - engines have been changed though?!

Replica - 2/3 scale, full size but large sections with changes -
engine/avionics/undercarriage/construction. Some of the kit ones.

Therefore I would not say 3579 was a replica as it was a 95% complete aircraft to start with. 1407 is a bit different as it was largely rebuilt.

Sure other people have there ideas.
