In my opinion, none of the canes are Murano. And I don't think the piece was made outside of Scotland.
Many (or was it all???) of the canes used in the Caithness-made weights for Edinburgh Crystal were pulled by John Deacons who was contracted by Caithness to produce them. And those same canes can also be seen in a variety of John's own work. And they also look broadly similar to some original Whitefriars canes. The very "coggy" canes in two rows in the bowl are rather like those. But I do not believe that the goblet has anything to do with Edinburgh Crystal or Caithness - or even Whitefriars.
The canes in the foot that have the eight alternating canes are of a style often found in Perthshire Paperweights items and also Strathearn Glass pieces from around the 1970s. I have no idea which company first began to use that style but there are a lot of those canes around, from both companies - and in a wide range of colourways and central elements, including central crosses. Also they both used canes with individual elements using a 20-rib outer "cog", such as the in the central cane bottom right of Alan's photo of the foot.
My guess is that the glass was out of Perthshire Paperweights - but I would not be too surprised if it turned out to be by somebody else who had access to that range of canes.
