No rest for the wicked, Eh Woody! I like the box illustration, with the combination of Sand and RLM 65, but i've no idea if that's accurate or not. Good luck with the build.
Not RLM 65 but RLM 78.
I've modelled this one myself and despite superficial appearances this is not a standard tropical scheme,probably due to a re-paint at some point between its initial delivery and its assignment to Marseille.
Here's a few things from my notes.
Oil cooler warning inscription painted over (Styling differs)
"Hier Aufbocken" below lower reinforcing strip at fuselage/empennage join hand lettered (not stencilled) over new coat of RLM 78.
"Reifendruck 4,5 atu" on rear of fuselage was masked during re-paint and had its original RLM 78 background.
No fuselage frame numbers (what a relief!)
Component data plate on port fin (between rear of swastika and rudder hinge) painted over.
No upper wing walkway lines.
Oxygen filler and electrical socket advisory markings painted over.
The fuselage area behind the "Kennziffer" 14 has been re-painted,presumably to cover an earlier number or maybe the "Stammkennzeichen" and contrasts slightly with the rest of the upper camouflage (not on my model it didn't,after a few gloss coats etc)
Whitewall (conducting) tail wheel tyre. Don't know about the mainwheel tyres,you're in "prove me wrong"territory.
Fuselage "Balkenkreuz" look a bit uneven or streaky,maybe brush painted?
As implied above the fuselage/empennage join external reinforcing strips were present.
No upper,curved,head armour
No armoured wind screen
Propeller (VDM 9-12010,narrow blades as you'd expect on an F-4) were well weathered. Paint scoured from the fronts of the blades (the surfaces facing the rear of the aircraft).
Good luck with the build. H-J Marseille was a remarkable man,undoubtedly one of the great fighter pilots of the era.
Cheers
