It's the excellent control over the small details in the murrines has me a bit stuck on N S-C for this.
And the 4 prongs and the same shape of stem as mine. My photo doesn't show the bulge at the bottom of the stem as well as it is in reality. It's very definitely there and a feature of the design.
Have you finished watching Blown Away? Chris Taylor had real troubles and difficulties trying to add vertical canes to the bottom of a vessel, he wanted those to come down to a narrow base, as your goblet is. It turned out to be far harder than he had anticipated and did not go well for him.
Getting those murrines into the tiled sections, adding them to the bottom of the bowl and smoothing them in to a narrow base is something that would be extremely difficult, even for a very experienced, brave and experimental maker as Chris Taylor is.
Both N S-C and GE do cover a lot of different styles. Base finishes on N S-C pieces do vary too. My two vases have flat bases, one looks satinated, the other is kind of wheel polished, it has left a semi-circular swathe of wheel marks all over it. The signatures are on the sides, not the base.
Who else did use a 4 pronged tool?
I've just had another thought. Murrines, tiled like this, into a wall of glass like this, are found in some Vistosi birdies, are they not?
