Help With Glass Egg & Beleek Mark

[tyman91]

I know this Egg is over 25 years old, it was my Grandmothers. Would anyone knw the age or maker?

I know nothing about about Beleek. Can someone tell me when this mark is from please?

3rd green mark c.1965-81. It's gorgeous.

To be clear, the Belleek mark didn't come from the egg!
