yes the bowl has a lot of horizontal striations & there are a few faint vertical (more diagonal up the side) striations, & is definately lead crystal (a nice long lasting ping). it does have a greyish hue, but only slightly. base has a few bubbles, thick and not completely round.
I have attached a few more pics. I guess after reading further it could well be georgian ? but I wonder what period & what kind of glass it is ?
