I bought this yesterday. I had seen it before, (not the signature though!) but as a certain gentleman was "hovering" over me, daring me to buy any glass whatsoever at all, I left it behind.
But I went back yesterday and had a slightly better look and decided it was nice enough to pop in my brother's yultide stocking for putting trifle in.
While cleaning it up at home, I was starting to suspect a rock-crystal beast, rather than just cut crystal; and one of the dirty bits suddenly turned into a legible J. Lloyd.
It's *not* going in my brother's yuletide stocking!
It's a post-war thing, the mark has the Made in England surrounding the Tudor.
Nightmare to photgraph. It's a nightmare to wash and dry too. I've gone right off it already, so I will not be using it for trifle either.
There are very deep "monumental" cuts, but also some very fine intaglio work, which does not show up well.
