I don't think these ones are Gullaskruf, which have much more tapered and slightly longer (in proportion to the rest of the bottle) necks.
I've got a pale blue (cased over white) one, like yours, and a deep red one with a big round dent in it. I'm digging in the most remote areas of long lost memories, I've seen one with a label (can't remember if it's mine or not) I think it might have been Alsterfors - but I may be completely wrong. I'm afraid mine are all packed away, I've not a clue which box they're in either.
I don't call these bud vases, bud vases have round, often solid, glass bottoms, often with bubbles in.
These are long-necked bottles or flasks.
However, Pat (Bubbles) might be able to tell you if these are ever described as bud vases. Pat's the Bud Vase Lady. :thup:
