Hello,
I tried to add something about this on Whitefriars.com, but for some reason it kept asking me to register when posting my comment.
Certainly not Whitefriars, nor Keith Murray

To be honest it's not even pea-moulded since the scale is wrong - the moulding is much too large.
Most, if not all manufactures in the UK made timbler/bucket vases and often one or more of a manufatcurers range would be the same size as another's. Sizes being popular with the buying public, etc.. The colour of blue used in the vase is also similar to blues recorded as being used by Thomas Webb, Stuart and Stevens & Williams, so the world's your oyster

However, IMHO, this is likley to be by Webb - indeed my own version is in one of my 'Webb' crates

Cheers, Nigel
