Part of the problem might have been when a particular engine was suggested...a radial...and that picture didn't look like an airplane with radial engines.

Yes, Hesham, good questions. They were airplanes and sailplanes. Not all of them were done when at Macchi. Most famous of all is the EB.4, which was a "people plane", a little canard (canards were always a keen interest for Bazzocchi; he started to use them anew in various configurations of the MB-340 and 341, and in the ATX and derived projects).

Uh, regarding the radial, yes, the design of the cowling is very streamlined, but the notes by Bazzocchi explicitly specify Alfa 135s. Keep in mind that the one shown is a conceptual early design, that  wouldn't have been possibly built by a company like Macchi at the time (complex, dual curvature surfaces, etc). In the following refined designs the shapes were less streamlined and more "buildable". The basic idea of the project was to marry the lifting fuselage idea from Burnell with the streamlined contour from Miles (Burnelli's and early Miles X projects were well known in Italy at that time, since they had been covered in magazines like L'Aerotecnique and Flight, that were widely read in Italy in the aeronautical coomunity).
I'm scanning like mad, tomorrow I'll start to post EB.9s.

The C.3 was another kind of beast. ok, I'll post that too... :P
And the EB. was earlier than 1944.

Ok, here we go. In late 1942 Bazzocchi modified the first configuration of its assault transport in a way more manufacturable by Macchi standards. In so doing, the design became more angular and apparently lost the ability to load and unload cargo via a rear door in a roll-on/roll-off fashion. Intended engines were alfa 135s.

During 1943, Bazzocchi revised further the lifting fuselage concept trying to recover the rear-door roll-on/roll-off capability. The result was a high-tail four fixed wheels configuration. Span was 32 meters. This design was roughly contemporaneous of the SM-96 III, a twin-tail assault transport maybe done for Germans (SM transports were high valued by the Luftwaffe).

In 1944, after a lot of aerodynamics research done at the Milan's Politecnico wind tunnel on the lifting fuselage configuration, Bazzocchi completely changed direction. Maybe the assault transport requirement by Germans never materialized, or he was already thinking of postwar development. In any case he chose a rather conventional configuration with a frontal cargo loading door. Landing gear was still fixed. This is the last known drawing of this project, but there is still another parallel variant with a distinctive shape that will be rather a surprise....

A very intersting design evolution.
