Lt Col. Robert J. Icks, Tanks and Armoured Vehicles. Phillip Andrews Pub. 1945
This was Germany's first light tank, designed in 1918 as an alternate to the monsters being constructed during WW1. It was based in a Daimler car chassis, with front engine and the driving compartment and turret behind. After the Armistice the two prototypes were destroyed but the plans apparently went to Sweden where they formed the basis for their Mark 21 tank.
