Hi Frank,
I don't think that it is Hungarian. The pieces that Sue was referring to are studio glasses, your pieces is more like made in a factory although not in large numbers.
If someone is interested in the exhibition at the Broadfield House: I will be there tonight for the private view (6-8 PM) and also give a tour on Saturday (30th May) starting at 2:30 PM.
The Japanese and Chinese piece that Chris mentioned is £4,600 (not 5,600). The price of the exhibited works ranges between £900-21,000. The Lugossy piece is a rarity, the artist has passed away in 2012 and she has pieces in the Louvre, British Museum, Corning, and many major museums.
