I did see this thread when it was first posted and I have waited for other folk to offer views before I made any comment. Truth is, I don't know for sure where those canes came from.
I think it is a bit unusual for an item to have canes included that are the same colour as the main glass. And that colour (watery dark teal???) is one that I do not recognise.
There is one cane (with the "teal" colour") at the top right in the initial image, that has a structure that seems to be quite similar to a Whitefriars (pre-Caithness type) structure cane. And it is also broadly similar to some canes used at Caithness Glass, and in some Edinburgh Crystal weights and also some items from John Deacons, in both his "JD" and earlier "StK" items. But on close inspection, it is not one of those.
The yellow and red colours are of shades that in my view should never be placed together in the same item. It reminds me of lots of mid-20th century Murano weights that have those ghastly (imo) yellows and oranges in them. The "cruciform" canes (again with that strange "teal" colour) are not what I am used to seeimg in Murano work - but that does not mean they are not Murano; I just don't recognise them. I suspect the canes are actually modern-ish Murano. But as we know, modern Murano canes have been sold around the world and plenty of makers have used them.
It may be worth moving over to Paperweights for further input.
