I have a Kieninger movement with 05 K on the back along with 116cm for pendulum. The clock is from the late 1980s, purchased in Germany. It is a triple chime with chain. Is there a replacement movement for this model? I don't see such a model listed with folks selling movements. Is there a another number somewhere that provides a better description? Did Kieninger use plated pivots during the 1980s?
