I tried acrylic in making my own frame.  Unfortunately it wasn't very successful.  It's just to easy to crack on a hard landing, and it's quite a heavy material.  I like the picture though. ;-)

There are many grades of acrylic plastic. My guess is that they have used one with semi hard rigidity. Also if you look at the pictures all corners are rounded so that there are no sharp edges. That removes stress points, preventing cracking and tearing.

It must be cold in Germany...

Depends on acrylic thickness too.

If it's thick it will survive. Otherwise, expect a win-fall on spare parts for Robbe. Though it does NOT look like extruded acrylic (easy to break), probably cast.
