A leading North Yorkshire auction house ( don't know if it's the same one though) has been responsible for many a mistake regarding "Whitefriars" pieces!! I've come up against this before.
When I saw it up on the Whitefriars .com site, I thought solifleur, as well, but most definitely not Whitefriars.
I like it a lot, and no idea how much it may be worth as a solifleur vase, although I've seen the odd one on e-bay making quite a bit.
Chris if you are trying to collect Whitefriars, then my best advice is to scour the catalogues on the .com site time and time again until you get a confident feel about Whitefriars shapes. It is a brilliant facility of the site worth its weight in gold, and will help prevent expensive buying mistakes!!
