Definitely English, most likely Walsh Walsh. ...
Most, perhaps all, of the late C19 and early C20 use of canary glass by Walsh that I've seen has been in combination with other layers of plain flint and/or opalescent, or Walsh's mother of pearl. Walsh's canary on its own was strongly coloured, so I surmise that they tried to moderate the effect by combining it with other glass. See the bottom end of the trumpet flute where it joins the base
here (click on the bottom right close-up). You can see both the strength of colour and the thickness of the flint casing. Only around 5–10% of the glass used was canary in this example, and the outcome is a lovely gentle colouring, enhancing the enamel and aventurine? inclusions. Any stronger and the canary colour would have swamped the inclusions and frightened the neighbours.
I agree with Ivo — that Walsh is the obvious starting point for attribution. I do have some unpublished Walsh material, so will check it this evening. Has anyone checked the factory pattern books, reproduced in Reynolds?
Apologies for not looking at this topic before. Bulb vases switch me off! Someone should have alerted me.
