It is not a colour that I associate so much with Scandinavian glass but there are generally exceptions to every 'rule'. Strombergshyttan certainly used the colour and I would guess others did and it looks as though Kosta Boda did too!
If it was mine I would certainly call it Kosta Boda, I had my green one for two years not knowing who made it. Then I saw another one with the maker's sticker still on it and I was a happy glass nerd.

I think the base of mine had a polished pontil (I sold it so I am having to rely on my addled brain).
