Crystal port glass - Welsh Royal Crystal

Hi

I've been trying to identify a glass I broke and have trawling round various forums, websites and social media hoping for help, so fingers crossed...

We now have one of a pair of port glasses, courtesy of my clumsiness, but they are proving very hard to identify. I found a copy of the makers mark on another website, but it's noted as unidentified, but as I have no idea how up to date the site is, I have to hope someone else knows:


It might help of course to see the glass itself. These are thumbnails of the remaining unbroken glass (click for larger versions):


Fingers *and toes* crossed...

Thanks
