It would be representative of a late G-2 as the wing bulges were added to late production machines, the antenna lead in on the fuselage is above the fuselage cross, correct for a G-2, on a G-4 it goes in to the rear of the fuselage in the last section ahead of the tail assembly.
and it is painted in the markings of Marseille...is it absolutely correct....not sure need to dig out my reference book...
