This is Favorit’s all plastic version of the Favorit Special. This design went on to be adopted by Walter.

Note that the parallelogram pivots are held in place by distinctive ‘double cirlips’. This is different from the Favorit Special and the all-plastic Favorit models that I have seen but is consistent with all the Walter models that I have seen.
