Green vase - Scandinavian?

Can't seem to find this one anywhere. It's about 13" tall, and one of a pair (very slight difference in depth of colour between the two). Thought it might be Gullaskruf but I think it's the wrong shape. Anyone got any ideas?

Still no luck identifying this. Anyone?

*bump*

This is driving me nuts! Can't find anything about these. Someone must have a clue!

A photo of the base might help, but I haven't come across one this shape so far.

The base is kind of a concave indentation rather than a pontil, and there's evidence of concentric rings there. Some age, too. Photo to follow.

I may have found it. Type Gullaskruf Glass in Google and a number of similar ones pop up in different colours.

Yeah, you see I initially thought Gullaskruf when I saw them, and that's why I bought them. But I've not found reference of this particular shape: these have a very particular flattened bulb, where it's squashed from the top - the Gullaskruf examples I've seen tend to be squashed the other way, if that makes sense! They have got that kind of flared neck though.
