Dear AutoPuzzlers,
I have to excuse myself to all of you, who tried to find the right solution for the coachbuilder of this bus.
Yesterday I found a second and much more reliable source, which describes this bus in all its details very carefully.
The coachbuilder is "Ernst Auwärter", as "pguillem" stated with one of his replies correctly.
So we have:
Make: Mercedes
Coachbuilder: Ernst Auwärter
Still to find:
Designation?
Type and special feature of the chassis?
Year?
I think, it will only be fair -due to my mistake- to LOCK for "pguillem" for three attempts to find the remaining answers
Sorry once again
