Hi Chrisffc, well he is a cutie, but not Whitefriars. Also, ti help rule out some others, not Wedgwood, nor Langha. These are the ones I can be certain about.
It probably isn't that much help, but at least ruling some makers out is a start.
The base may be a big clue to some others.....I thought at first maybe Chris Dodds of Tweedsmuir glass, and if you can give a very clear enlarged picture of the base, I may be able to help a bit more.
