There is also an 'incision' in the topwing at the back, just above the tailboom. The only rason why this should be done is to give a crewmember / gunner a clearer view above. It could be that there were MG's in the tailbooms operated by crew members in the tail booms.

The machine was possibly devised as a battle ship escorting bomber squadrons. Be aware this is only conjecture, no factual data.

Paolo and Yavor, I presume that the pieces taken out of the topwing at the back are not the best in aerodynamics? Also the wings grow longer from lower, to middle to topwing.

Escorting battle ships (planes) were envisaged at the end of the war in the USA, I think for example by Burgess, but not really built.

As an afterthought. The relatively small size of this three-engined triplane might hint at the fact that the machine is not designed as a bomber, but primarily as an escort battle-ship.
