Re. Jindrich post:
I agree that this bowl of Antique Rose's is certainly Skrdlovice 1950's, a lovely piece.
Re. Andy's above post: No doubt on these Andy as Jindrich says yours are Jan Beranek design from 1958 - pattern 5988/30.
The previous thread this week was concerning the ones with the cut top (and some similar tall vases without a cut which you have only one of that Michelle used for the Sklo group shot on facebook for a while etc...) It was just my point concerning the cut top vases especially that Skrdlovice seemed unlikely, which you agree with "and the jury is still out" on these since documented evidence of any kind is not fully convincing.
All the others that you mention are, as Jindrich previously said, Jan Beranek design from 1958 - pattern 5988/30, I would agree, the proof is in many places,
all these vases it gets confusing, I was trying to keep things simple....
