I have a Herschede Tambour Westminster clock that has a movement that needs the chime silence mechanism repaired. The chime silence is operated with the key. Someone has wound it around until the brass arm is broken off. Are there any pictures of Herschede movements other than the pictures in the Herschede Clocks published by the American Clock and Watch Museum? The serial # on my clock is 6000.It is a Deluxe Model 10 Pendulum Movement #204, shown on page 149 of the above mentioned publication.
