Hey Jos,
I really like the photograph!
(Would have been a good candidate for "Breguet's Crash File"
)
But to answer your question: It appears to be a
Salmson-Moineau S.M. 1,
a french reconnaissance and bombing aircraft.
It was the first aircraft of the "Société des Moteurs Salmson" engine factory and appeared in 1917, if I am right. It´s engine was placed inside the fuselage and drove two props mountet between the wings through shafts coming out at these big round constructions visible at fuselage-side.
According to my data it is not known how many of them were built, but serials were used up to 124. 50 were offered to the british, who refused to take them.
But it is proven that some of them have been in service.
It probably was not one of the most succesful designes...
It looked like this from the front:
(the picture is not the best, but you can get an idea)
Cheers
