Briefly, Helen Monro married Professor W.E. Turner and took the name Monro-Turner. She was an engraver, both on glass and of pictures and designed cut pieces for Edinburgh Crystal before leaving and starting the glass department at Edinburgh College of Art. Most of her known glass work is clear. She was highly influential on British glass design. She also ran the
Jupiter Studio with John Laurie. I think it is therefore highly unlikely that your vase has anything to do with her.
I've not checked the detail, so if my memory has let me down, I'm sure someone out there will correct me

I too thought Hospodka, as a result of the King's Lynn exhibition
"Hi Sklo Lo Sklo" last year, and Mark Hill's book. The possible fresh attribution is very interesting. I look forward to seeing more information as you get it John.
