The first vase may or may not be Rudolfova, and possibly Schrotter.
The second vase, if my memory serves me well, appeared on this board in blue some time ago, and was identified then as a product of the scandinavian glassworks Ruda.
You should also be wary of Schrotter attributions. He was not the only designer for Rudolfova, and also worked in the UK in the 1930s. Other designers' work from Rudolfova already fetches extremely good money.
Simply having a deep base-well does not immediately make a piece Rudolfova, or for that matter any of the major Czechoslovakian pressed glass works. I have seen this same feature on Polish and Russian glass of the same period.
Also. be careful of this glass as a long-term investment. more than two thirds of ALL Czechoslovakian pressed glass during the period 1948-1990 went to Comecon countries and there is a massive amount of it about. Heppners(London) Ltd, the UKs largest importer of pressed glass from Sklo Union, in the 1960s were importing @ £2 million pounds worth of pressed glass per year at that time.
