Tall orange vase - any ideas?

Tall orange coloured cased vase - 13.5" tall with small foot and round section to base, tall neck - orange coloured casing.

Looks Scandinavian?

Any idea of orogin, I presume date is 60s - 70s

Thanks Adam

Before I start, please forgive me if I ramble on but look at the time The only good thing about insomnia is that it gives me plenty of quiet time for research.

I've been looking through some books and your vase is similar to both the Carnaby and Palette / Palet ranges, designed by Per Lutken and Michael Bang respectively, by Holmegaard (it also bears slight resemblence to some of the '60s Murano art pieces, but only very slight).
My 2008 'Millers Collectables' has a little info on Holmegaard, including the snippet that because the quality was so important to the Holmegaard works, any slight defect in the glass, even the tiniest of internal bubbles, made the piece a second, and as such was not signed on the base. So if yours has no factory mark but has a minor flaw, be it a bubble, striation, lump or bump, it could still be Holmegaard.
On a more depressing note, the book also warns about repro's from China and central Europe, which were made in abundance (I've never been to a bun dance, it sounds fun) in the 80's and 90's. They tend to be lighter in weight than the real thing, are not so well proportioned, and you can differentiate the colours if you can compare them 'in the flesh' to original pieces.

See, I told you I ramble on when I'm tired.

Definitely not Holmegaard, almost certainly Chinese.

It feels inferior compared to my Holmegaard pieces and its not got a clear casing - so I go with Nic
