Sorry Tina,
it is my Cz-English issue. I did not intend to tell you are not expert. I wanted to tell you, that everyone can easy find difference between old - pre-war and just after war Bohemian crystal and production of Bohemia n.p.
I personaly do not like both - but it is national heritage - every Czech family has collection of cut Bohemian crystal from grandmother :-). Never used, only for looking.
Jindrich
