As explained I'm pretty sure that Chance or Fiesta Glass never made such a plate. I'll keep checking, but nothing in my records shows one so far.
Getting one made specially is a possibility, but ideally the enamel transfer would need to be "fired on" and I very much doubt Tesco could do this... This is where the plate is heated to about 700 deg C so that the enamels get fixed to the glass, otherwise it could rub off or be more susceptible to scratching. This could prove to be a problem - not least financially.
Chance and Fiesta would only ever produce custom trays on a minimum run of 250 pieces, but times have changed. For example, after searching on the internet I notice that vehicle sign printers will print to glass, although whether that would produce a satisfactory finish is unknown.
I imagine a gold finish is possible, although I know these were never fired on as the gilt Chance & Fiesta used is actually gold and not an enamel. Perhaps a 'gold finish' has been reformulated to a much better standard?
However, as an industrial process I can't guarantee that any company would be prepared to do all this for just a single plate.
Sourcing a blank glass plate is the other hurdle. If you wanted one with the wavy edge, then it might be an idea to look for a Chance/Fiesta plate that has just a border decoration and get a transfer made for the centre. No idea who could make a slumped blank otherwise.
So plenty of ideas - not necessarily easy, possible, or cost-effective! Anyone with other ideas?
