Topic: Help please with id for this glass goblet

[palo400]

Hello there

I'd be grateful if anyone knows who this lovely glass goblet is made by.
It's really solid and heavy with lots of age ware to the base.
It's clear cased with brown, cream and white swirls and speckles.
It weights 1.3kg and is 14.5cm high and 11cm wide at the top.
Brown mdina? or maybe Scottish?
If anyone has any ideas, it would be much appreciated.
Thanks

Pretty certain it's not Mdina.
