I got a ride on one at an AMCA cycle meet. It sounded just like the movie! The guy was driving it crazy, over dirt piles, through holes, it was unstoppable. He said they built it with the motorcycle front to make it more familiar and easy for the troops to drive...seeing as how many of them were trained on and used to motorcycles. He also said that the handlebar steering actually controls the tracks like a skid steer, rather than the front wheel actually steering the machine. He said they were so popular as tugs that they were allowed to produce them after the war, perhaps into the early 1950's. It was used in agriculture and was not considered a weapon, and it employed Germans at a time of financial hardship in Germany. He said the wartime versions had nastier welds (Done by young kids or women, while the experienced men were fighting). Post-war units have nice welds. The wartime ones are more valuable to collectors, but I sure would take a post-war one in a heartbeat! Now if we could get somebody to reproduce them cheaply.....
