After I posted another topic about a blue overlay jug in what I think is the same pattern, my goblet arrived.
I've posted three sets of photos.
It's old, but how old is the question. Bubbles and tiny specks in the glass.
The bowl is 3 1/8" diameter at the rim and the foot is wider at 3 3/8"
The rim is very thick, cut and bevelled on both sides.
The foot is even thicker also cut and bevelled. The ruby overlay on the foot is cut in petal but the overlay is on the base of the foot not on top of the foot.
It's immaculately made so that you cannot see the join between bowl and stem or between stem and foot. It looks as though it was made entirely from one piece of glass.
The overlay pattern where the base of the bowl joins the foot is horseshoe shaped pattern, but doesn't show in the pieces because of reflections and the glass is so thick the paper wouldn't sit down any further in the bowl
It's a heavy piece.
Terrible photo, so I'm very happy with what's arrived. But would love to know where it was made

I've already done quite a lot of searching on Sandwich overlay glass as I thought it might be American (could only see a view from the top so had to guess the stem and pattern lol).
Please, any help much appreciated

Sorry for so many photos
