Thank You for you're help. I have just managed to find some information via the initial post reply. The item is :- Rudolf Jurnikl, 1964
Sklo Union, Rudolfova Hut, Pattern No. 13227/18.
Unfortunately, I do not have the book to confirm this pattern number. Hopefully, someone can confirm this as being correct.
Merci
