This tank paper model is the Mark IV, and the tank papercraft is designed by Wayne McCulough and from landships. The Schneider CA1 (originally named the Schneider CA) was the first French tank. It was inspired by the need to overcome the stalemate of trench warfare which prevailed during the early years of the Great War. More specifically to open passages for the infantry through German barbed wire and to destroy enemy machine gun nests . Four hundred Schneider CA1 tanks were manufactured by SOMUA, between September 1916 and August 1918.
The model is really difficult to assemble, so much so that Wayne wonders what the workers thought of the real ones as they assembled them. There are so many small pieces and odd angles. There are bulkheads supplied in an effort to keep the parts straight and aligned.
There are two hulls. The early hull had two fuel tanks - one in the bow and one on the left side next to the driver. These were found to be vulnerable to fire in combat. The late hull added two external fuel tanks on the hull rear.
Early and late hulls had applique armor added to parts of the front and sides. these parts are included in the models, though they aren't strictly necessary. [via landships]
