SPAD A2 Amodel 1/72 scale...

This monstrosity was a solution for obtain a maximum clean field to shot to enemy planes or balloons, in times when shooting a gun inside the propeller arc was not yet developed.
One can imagine the feelings of the gunner/observer flying in a cage just centimeter in front of the rotating engine in this fragile structure. Well, the French Command was not convinced with this machine and this model was finally soled to Russian Army...
