looking at that item in Roger Dodsworth's BGbtws, and another of different shape but same colourway which came up for sale in Lot One of the Michael Parkington Collection, there is a noticeable overall difference in the appearance of colour between those two and the one here. The two known Monart examples show an effect that looks like the pink blending towards blue, with a more subtle merging and mixing of the two colours, not the separate colour flake appearance as appears on Chris' piece. That's not to say this one isn't Monart - since I know less than nothing about Scottish glass - but just to comment that the appearance is very different.
The inner white looks to be o.k., and for all I know this inverted baluster shape may well be something that Monart did.
Back in 1997, Christie's catalogued Michael Parkington's example (the colour part of the description) as "milky body overlaid in speckled pink graduating to blue, cased in clear ......."
My thoughts are that Frank Andrews or Garry would be the guys to know best on this one.
