Thanks for the feed-back here all of you.
Glen, thank you for your suggestions, Rex is unlikely, and "Zwiebel Muster" I can discount.
Interestingly from Peter's contribution, the last paragraph on the Regional Museum Teplice site link he gave, specifically mentions "Boutique" and "Cibulak" and credits these to Pavel Panak. The meaning of Cibulak is "Onion". The former of these I am familiar with as it was an exhibited pattern at the 1st Internation Exposition of Glass and Porcelain held in Jabonec nad Nisou in 1973, reference image number 20, and was best press glass product of 1972. Produced Sklo Union Teplice, Rudolfova Hut.
