No.
As I tried to explain in my previous post I guess he won't be mentioned in the history of Maico as he only did a second role job there.
He actully had a
driver job, though.
Obviousely he worked at another not car related company as a mechanic later.
Further the source reports that he started on minor racing events, though I can't find him listed anywhere on the internet (so far).
Seems he was more a kind of hobby driver.
