An earlier topic on the board shows how tricky these are
Thanks for that link Anne, actually it was Vidfletch who bought the Italian ones at Cambridge a few years ago, and I was there with him.!!
This morning I did a Bark versus Glacier range reccy! The Bark texture is totally different to the Glacier range texture ( I wish I had one of the tumblers to photograph alongside a Bark vase to illustrate). Tracey's tumbler has the Bark-ish texture as opposed to the glacier texture, which rules out for me it being a colour version of the W/F tumbler. Also the colour of the tumbler under debate, is definitely not a Whitefriars Tangerine to my eye. So, at the risk of being boring, I still stick to my original position.! LOL!
