Last one for the day I promise. It's 210mm high. This I have down as Bohemian, possibly around 1960 and possibly Novy Bor. Never seen another exactly the same though, although there was one a while back on ebay that just had the lens bits, but not the cut lines. Have also seen the odd Russian vase a bit like it (there's one on the GMB as we speak).
I have seen one that was much bigger in this colbolt blue colour and a different shape with lenses, but they were poor quality - I presume they are acid etched in some way. The lens idea does seem to have been around for a long time in world of Bohemia, in dark red and colbolt blue. I bought this from a glass dealer who was unable to identify it. Any ideas of a positive ID?
