Ah, so there are multiple aircraft donating to this then...
Are they all from NAA products or other manufacturers?
Brilliant, Apophenia, you're almost there.
Okay folks, now it's time for the answer... Original photo was this:

1°) Manual rearward sweep of the wing, tail stabilizers and fin.
2°) Split of the underbelly podded jet and integration into nose and tail.
3°) Replacement of the wing pod's dual intakes by an F-84 Thunderjet's nose cowling.
4°) Addition of a wingtip tank snatched from an AJ-2 Savage.
5°) Replacement of cockpit by that of an F-105 Thunderchief.
6°) Modification of serial numbers.
7°) Recreation of a fake brochure using original "NAA", "North American Aviation" and "Savage" logos.
By looking at the aircraft's buzz number's prefix "BE-" I guess one could have found what type I used, since I completely forgot to modify it!!
