Those "Pionierpanzer" (as in the Communist Young Pioneers, not Armored Engineering Vehicle) were hand-built roughly to a 1:3 scale from welded boilerplate by a subdivision of the People's Nitrogene Plant Piesteritz on the initiative of some guy running the "Young Tourists Station" in nearby Bad Schmiedeberg. They were powered by a Trabant 601 engine in the back, including the original gear and fuel tank, top speed was about 15 kph. Brakes were also from Trabant or Wartburg cars, steering was by levers acting on band brakes. Turret couldn't traverse, gun was fake, "firing" and "hits" were simulated with flash devices. There seem to have been just a handful of them resembling various actual types.
