Hi John,
That's a shame, I thought I'd seen tumblers like yours listed under Moser on the Great-Glass website shown in their Photo Gallery. I've had another look and one difference I can now see is that on the Moser examples shown the gilding does not cover all of the glass surface like on yours, there are gaps where the main colour shows through.
Pity. It's a nice piece.
Cheers,
Bryn
