Some excellent stuff to go on there, I agree with all you say. The optic vase is 1.6k in weight the base is not that thick but it is tall and the walls are not thin (4.5mm).
I also thought looks so Chihuly with the opalescent shell like piece (the blue piping), I have had the pleasure of handling his Shell forms and they are not as heavy as this, and also I should be so lucky!
Thanks for the Borske Sklo / Chrbska info, I have no good older reference books on Czech glass, I will buy 'Jackson's Factory Glass' at Borders I think, I have looked at it often enough.
I am buying books but they are expensive, I just bought 'Glassware Glasswarren Verreries Vetri Di Murano - G Mariacher' for £40.00 second hand (12.000 lire when new) and have a good local source for such books but I will be taking it step by step, I have a lot of the new reference books, it's the older books I want to acquire - this Murano book is amazing with excellent text (in Italian and English phew).
The bottle, the stopper is very Hoglund, but that blue bottle shape is almost like a square Kuttrolf, colour matches up to my Kastrup one, but designs were so similar.
I should get down to the Mitchell Library, its near me and one of the biggest design reference libraries in Europe.
Thanks again Peter
Also bought some Italian Paperweights, will be posting in that section soon.
