Vintage Theodor Heuss Graupner model build early '70 by a masterbuilder,
clock work like spindel and e-switch system on 6V. Spindel is driven by Miliperm Pile getriebe, Heckklappe with regular toy motor.
It is to be revised on detail and wiring, hence to old age....
This movie was made to illustrate on a modelbuilders forum,
and is part of a rebuilding, restoration process...
