Another eBay buy, which (with my very limited knowledge) I think isn't Whitefriars.
Hopefully someone smarter can confirm or tell me I'm wrong.
In the attached pics, 1 is from the listing - and it seems ok in that pic.
But 2 shows the shape to be less domed than usual.
And in 3, the base doesn't seem as sharp as usual; and those grooves are something I've never seen.
