To those of you over the pond

this may not be a hugely interesting discovery, but for me...I was so excited to get this. I would have preferred a yellow version, but this is nearly as nice.
I 'thought' it was a Fenton Florentine stretch bowl, however, I can't find one in 10 3/8" width and having looked at a previous post of Christine's and a link on there, I'm now wondering. The rim is crackled, rough but not damaged, and it doesn't look like the smooth one apparently id'd as Fenton. As I say, I also can't match the width of the bowl.
The foot is 3 3/4" diameter and the actual rim width edge to edge is 9 1/4". The base is a deep hollowed out 'cup' within the foot (sorry I forgot to take a pic)
I can't find those dimensions on Diamond Glassware either

but could it be a Diamond low cupped bowl?
Thank you for any help
