Yup, it’s the tie down tubes the rope passes thru in the lower surface of the wings 🙂
That would’ve been my second guess 
Stormbird takes the palm thus far. Amazing how many of the ugliest aircraft imaginable turn out to be of French manufacture. Case in point the Morane Saulnier ANL.
How could the same people that built some of the most elegant aircraft of The Great War come up with this? Generally I take the view that there is no such thing as an ugly bi-plane, but the French really pushed the envelope with the Morane Saulnier AN series.
I have a picture somewhere on a disk, of a Short shirl torpedo-bomber(no good for Quize’s with it’s name on the side :rolleyes: ), with mod’s to fly the pond back in April 1919,
called the Short Shamrock, with a huge tank underneather instead of a torp, and bigger wing span, It has four guy’s linked hand in hand to throw the HUGE wooden prop for contact,(if someone has it handy post it please 😉 )
This looks like it.
And here is the unmodified version. With appologies for the retouching which was done for a spoof web site of mine.
