Fascinating! Never noticed that before.
Looks like there's at least 2 Panther engine decks there.
I've also read that there's most of the transmission from a Porsche kit (no idea which type
of Porsche, or what scale) incorporated into one of the side panels on the Falcon!
Looking at that large pic of the MF's upper hull, I'm sure I can see some other bits
from tanks and military vehicles... that rectangular grille to the right of one of the large
round exhausts definitely looks like the engine cover from a post-war tank/AFV of some kind (not sure which one).
