Hi this glass is quite large, it's just over 8" tall, nearly 9" wide and up to 5" deep. It's not symmetrical, and is in a blue (which is encased in a clear blue towards the base) with random black speckle inclusions throughout which to me, look like soot deposits. The 2 middle images are truer to the actual rich colour of this. In the polished Pontic mark, there is a clear hand signed signature of William Butler, with a fainter hand signed William Butler signature offset below that. To me, this looks a lot like the shoulder Vase minus he vertical decor? It's a heavy item, my luggage scales make it 3.8 kilo. I've tried to find William Butler signatures on the internet as I know William Butler worked at Whitefriars in the 30s and 40s and this definitely has the look of Whitefriars to me. Can anyone help me with info about it please? Thanks
