Bü 180 Student with enclosed cockpit?

[Dénes Bernád]

The family of the late Fw. Scholz (see the other thread) gave me a pair of photos showing him in front of a sports airplane with enclosed cockpit.
I would have not recognised the airplane type, if the name would not have been written on the engine cowling: Bücker Student.

I was not aware of the existence of an enclosed cockpit version of Bü 180. Can anyone give us details, incl. possible civilian markings?

Thanks,
