I should add, I'm not unwilling to believe is it Riihimaki and by Tamara Aladin, just stylistically, the flat square edged foot, which looks applied, is unlike any Tamara Aladin, or Riihimaki I have seen.
Sure, there are similarities to Riihimaki pieces, including the Hurricane vases- but they have a rounded edge to the foot, which is much thicker, and the transition in the casing is more organic and softer...
