Thank you guys for your replies. What i know is that it is surely before 1966 because it belonged to my great grand father who died that year. So probably it is from the 30s as CanadianBottles assumed. If only i could find which company made it and from which winery came..
No way to know the original brand of the contents I'm afraid, the marking on the bottom refers to the glass company. I imagine it's possible to figure out which glass company it's from but I don't know anything about UK marks personally.
