Ross,
You clearly don't know the rules for IDing glass for sale on ebay, they are:
1) If it has a Ground and Polished pontil Scar, it's Whitefriars.
2) If its Textured, it's Whitefriars
3) If it looks remotely Bark like, It's Whitefriars
4) If it has controlled Bubbles, it's Whitefriars
5) If it's a Duck/Owl/Elephant, It's Whitfriars
