I'll put a pick of the two I have, I feel the smaler maybe older and looks like Rachael's, I'm in Venice at the minute and it's stuffed full of Chinese glass, I get the feeling things are really going to get difficult for all of us in the future, the labelled amber one I saw had a Krosno label on it, I did not buy it as I already had two which are going up for sale when I get back so fingers crossed they might get a positive i d.
After spending today in Murano it's also has a lot of Chinese glass it's either sad or a modern reflection on mass produced goods, you can walk around Murano in about an hour so how on earth could they produce tens of thousands of pieces of glass yearly.
