Only the Germans would be so thorough.
At first glance one might think flyweights equalled centrifugal timing control, BUT IT DOESN'T. The timing is map created to the conditions that exist. The spark is formed and the distributor's job is to get it to the right terminal of the cap. You will notice a very wide rotor tip and a large diameter cap (terminals widely spaced). To anyone else (and to all MB's built after, M103 for example) that would be enough, but MB had added a cent. advancement of the rotor position to maintain the gap in a similar position and length as the timing changed. If it didn't the rotor would be in a different position relative to the terminal when fired.
