Gets more and more interesting. Now we have Bayel and LSA. I have both, a marked piece of Bayel and a labled LSA international made in Poland. In comparing the clear parts of all the pieces, I notice that the slipper bath and wobbly bowl have minute bubbles whereas the Bayel has none and the LSA one stray one. This leads me to conclude the quality of the glass while minor, is different. Now whether this is important, I really don't know. But I have to add that Tiger stop, or you will corner the market on these. Terry
