Not sure about the ebay item, I would not think of it as Skrdlovice. But this GMB member bowl looks like a definite Beranek pattern probably by Jaroslav Beranek. He designed pieces, over several years at least, that were later collected to form the "Andromeda" range. However, other relatives within the factory made some (wonderful) similar patterns at the same time. GMB member Jindrich can probably confirm, deny or clarify a little further! To demonstrate the similarity of designs this attached image is probably also a Beranek bowl-jardiniere probably not Andromeda. It is 31cms, 18cms, 10 cms. I have an Andromeda bowl-jardiniere that is more typical in colour, dark blue-green-clear, that is 40cms. I like all the Beranek family output I have seen from this period, all of them had a lot of talent. The colour of the GMB member bowl is unusual but sometimes different mixes of colours made for lighter-darker productions on different days or months and unusual colours do happen especially with the 1950's production era,
