Where was this bullicante lamp base made?

Hello, Can anyone help ID this bullicante small and heavy table lamp? I bought it on a flee market. Size is approx 9.5" tall. I asked some information in a Facebook Glass-group and there someone told me that 95% murano would have a flat polished base. This lamp base has a pontil mark. If it isn't Murano where is it made? All suggestions appreciated. Thank you a lot!

Looks like a British lamp fitting, and a British PAT label.
Maybe take the out of date label off, there may be a mark underneath.
Webb might be a possibility.

Thank you al lot! I took of the label to see underneath but it does not seem to be a mark. But now I can search more specifically, direction Britain.

The fitting isn't original. Clearly a modern replacement and a red herring as to origin I think.
