Modernist Rosenthal vase - can anyone ID the designer?

This Structural glass vessel executed by Rosenthal,Germany.
Geometrical form,bottom section and top section are cylindrical and middle is cube.

It has very thick walls and polished base.Marked on base with manufacturer acid stamp .
Rosenthal employed number of designers who worked with glass and ceramics.
I was hoping to recognize designer style/signature in some Rosenthal Ceramics I've seen,
for instance Winblad's ceramics,they've got have great deal of similarity with his glass designs.
So far no luck.
I emailed to Rosenthal,unfortunately they were unable to
provide any information on this design.
I hope someone will tell me who designer is.

It's a lovely vase however if Rosenthal themselves can't tell you who designed it's probably a very long shot that anyone else can. I'll convert your photos to image links rather than clickable links so the vase is visible on your posting and alter your thread heading to make it a little more informative in case someone who knows more might come along.

Tapio Wirkkala did submitted lots of designs (glass and Ceramics ) for Rosenthal AG 1956-79, also michael harris did commisions 1970-71, I am not saying they had anything to do with your piece but who knows , surprisingly not rosenthal.

They employed a whole heap of brilliant designers - a list as long as your arm! This vase isn't indicative of the work of either Tapio Wirkkala or Michael Harris however...
