Ribbed iridescent rose bowl XL

I thought this would be Kralik when buying online without a base picture. The glass I finer than I expected and the snapped pontil mark then made me question my assumptions. So I now think generic Bohemian Art Nouveau unless anyone can help? Maybe Rindskopf?
Despite being "damage free" there is a large chip beneath part of the rim - one of the dangers of buying online from non-specialists, I suppose.
It is 20cm across by 13cm high.
