swiss table identification  

hi all,

picked up this rather nice table made by girsberger in switzerland and was wondering if anyone knew who the designer was.

it's dated from the 60s (as you can see on the photo of the guarantee) and it was bought with a set of four chairs by ernest lauclair. i know that dieter waeckerlin and hans eichenberger were both working for girsberger at the time but this doesn't seem a good fit. i believe that girsberger were also producing pieces for knoll international at this period ... could this be something from florence knoll ?

thanks in advance for any help !

cheers jonny
