Treffas-Wagen

After the British Army introduced the Mark I tanks on the battlefield for the first time in September 1916, the German War Ministry responded by ordering several German firms to design and produce a prototype for a similar war machine. One of the approached firms was Hansa-Lloyd based in the city of Bremen, which came up with a working design. Ten prototypes were planned to be built. The engineers of Hansa-Lloyd, having no experience with designing either armed or armored vehicles, came up with a big-wheel design which they called Treffas-Wagen. A single prototype was completed on February 1, 1917.
