Oh my, this is interesting ! :hiclp:
Andy: I am a Finn and somehow doubt the "Scandinavian" guess because I haven't seen anything quite like this before. "French" I could buy, but no signature in this one. Well, it seems there are a lot of possibilities, like at the moment - all of them. (I would love it to be Czech - "flying free" -

but somehow doubt that as the base ring is not matt?)
glassobsessed: I bought this from a fleamarket here in Finland - it seems there are a lot of smaller foreign objects available I suppose they were handy to take home as souveniers. Hard to find for example larger vases which is a pity.

Your lampbase has similarities ! Especially if the dimples are in symmetrical order ? And how about the base finish?
Lustrousstone: Really not even the slightest tint of any colour in this one. But would really appreciate you checking if it is possible.

Also looking forward to getting any other views from you experts.
