The clearity of the glass makes me push towards a USA made classic of some sort.
It has big bubbles though and one not quite finished cutmark--kinda ruff really.
If the second image on the left if a cut-line along with the third image on the left--a slight "V"--Vitro--no name.
Nice find--no better ID from me at least.
@Ric is right on again.
Marble--On!!
