Thanks Ivo, now my head hurts ! The bonus in searching your clues is seeing so much stunning glass. I do get side tracked by certain pieces. I am no closer than saying it is Scandinavian. Lots of similar engraving and colour. Not seen this shape yet though. I like the colour on this piece, held at certain angles it shows clear. Could this be a cased clear over a blue or just a hint of blue in the glass ? I am not home right now so cant check. ill keep searching. Thanks again.
