Slots below rear fin on F40

I believe that some of the F40 prototypes featured the 5 slots.

A lot of times diecast companies are given access to prototypes for their modeling efforts so the details they capture may not be 100% true to the production cars. That gets carried over to their finished product and sometimes leaves enthusiasts scratching their heads.

The Maisto McLaren F1 is the same way with a few details that don't quite match the production F1s.

Yup, the extra vents below the sides of the wing were only on the prototypes....

 

Here is an F40 that features both a prototype 5 vent rear fender and also some USA F40 bits...

One more view of the same F40.
With only a mirror on the drivers side mounted in the early position (not down lower on the top edge of the door) could this be s/n 73015? Saw this F40 but can't recall the serial number. The car by then was about 7 years old and had been freshly repainted.

Which style of rear window does the model have? The first picture in post #4 clearly shows the flat rear window with small slots. The later production version had the slots indented and of a different shape. 18 slots for the early version but only 11 slots for the production version.

That's odd, I think even the prototypes even had those 6 slots below the rear wing.
