Whitefriars 6 sided vase

I know is Whitefriars production in Kingfisher Blue - what I can't work out however is the pattern number - I can't find it in the catalogues. I know there's a rare 8 sided vase - I've had one in the past - which is very similar to this, but this one only has 6 sides - does anyone here know the pattern number of this one?

Its a new one on me Pip, never even heard of a six sider i've had a good look through books etc and can't see it. Is there any chance its not WF, or does it have all the right factors to suggest it is?

I can't find it either Davee (thank you for looking) - I'm 99.9% certain it is WF - I've handled so many pieces of WF now and it's absolutely right in all respects - the only thing not right is it's not in any of the catalogues...
