The Delaunay Belleville was an improvement of the FT concept and the prototyp was built after the WW1.
The drawing looks more like an hypothetical developpement of the Schneider design.
"Using their experience with the (artillery) tractor, Delaunay-Belleville began working on a medium tank on its own initiative. They decided to not reinvent the wheel: the medium tank completed in 1919 looked like an enlarged Renault FT. The front and turret were taken from the predecessor with no changes. The weight increased to 15.8 tons, which required a new engine and a hull that was almost one meter longer. At the same time, the hull was made wider. This was not caused by the engine, but by a 37 mm gun being placed in the front, to the left of the driver."
The Delauney-Belleville design was offered as an entrant in the Char de Bataille evaluation but was ruled out and never participated in the 1924 trials.
