Identify this Scandinavian sapphire blue cased glass vase

Hi everyone

I wonder if you could help identify this sapphire blue cased glass vase with a slightly curved or wavy form.

I’ve been told it’s Scandinavian and stands 20cm tall with a small ground/polished pontil mark.

Thanks for your help.

It's possible your vase was made in Sweden by Strombergshytan for the British import company Elfverson.
One of the leading lights in that company was H.J. Dunne Cooke who also had strong dealings with Whitefriars glass.
I'm only saying possibly because the picture in the catalogue gives a height for your vase 6''=150mm.
Is your vase heavy and thick walled?
Nice item of glass.

Hi Tim
Thank you very much for the detailed information!
The vase is heavy and thick walled, especially at the base. I’ll have a look into your information and see where it takes me.

Thanks again, much appreciated.
