Greg, could you email me too, please? I've lost/deleted your email address, (after downloading your images of course) and I have stuff to send to you...
I've just checked my Benny book, she was at Hadeland from '55-'67; Randsfjord from '67-'70 and Plus from '70-'84.
I imagine that's all a bit rough, because I can make out she spent time in Murano, and she may have worked with Timo Sarpaneva at some point. Sadly, I can't read Norwegian.
I also imagine that her designs were carried on after she left Randsfjord, because pieces in this colourway (and the related designs which have an unusual partial casing of a layer of strange grey-ish metallic stuff) are certainly the most commonly seen Benny pieces.
