Hi Della - my apologies for not being in a position to reply earlier (sad, family circumstances have meant that I have been away from home).
I believe that the pieces you have here were made in Czechoslovakia. Other shapes are known, as well as the powder jar and ring holder that you show here. The pattern has been called "Rib" (inventive....not
) and it is known bearing paper labels with Czech attribution. The actual maker is not known.
Rindskopf is in the frame, I suppose - as is the "unknown maker" that I'm currently working on.http://www.geocities.com/carni_glass_uk_2000/Tantalus.html
Hopefully we will get closer to an answer as time goes on.
