rmmagow,
I can only give you an answer for my type of Benz.
It is a W124 and the star moved to the hood when
the third Serie came out.
In Europ, that was on september 1993.
Don't know for the other types but will be about the
same period.
For the "S", the star moved with the arrival of the W 140.
Many greetings and a happy newyear!
Danny.
