Hi JP, I remember this bowl, it is indeed similar to Svobodova galaxy technique but various factors suggest quality Murano not CZ. The polished pontil rod mark is unlikely for Skrdlovice, I have never seen it on a galaxy range piece. Also a GMB member a while ago, Langhaugh I think, found a very good match for this bowl in a quite good quality import-export Murano catalogue from the 60's. He may remember a possible factory. Also, this bowl shape does not appear in the Skrdlovice pattern books as part of the galaxy range......... so in my opinion, quality Murano (sorry no definite factory!) is the way to go with it,
