Gorgeous design...
I've seen it at least once on ebay described as a Peill & Putzler vase, but I can't remember whether that one was marked or not, so I don't know if the seller was right. Sometimes the P&P name is used because they tend to fetch somewhat higher prices than less known makers. Most P&P vases are etch marked with the double P, but occasionally they only have a label, or no mark at all.
So I'm afraid the uncertainty continues... my feeling is that it is either from Germany or Scandinavia, though, 60s-70s.
