I was lucky enough to find a nice set of 6 glasses yesterday, I'm a sucker for old 'proper' glasses and I saw one sitting on a shelf, was going to buy it (I also don't mind having my glasses all mis-matched!) and then discovered 5 more on the shelf below so bought the lot. I believe they are cut crystal and are all marked to the bottom with an etched =S=.
After doing some research on the mark I stumbled on on message on this site saying that mark means they were - forgive me if I get this wrong - unmarked Stuart Crystal, and the =S= is a Stoniers mark, and they would have been used on board ocean liners back in the day (the = parts of the mark represents the plimsol line of a boat). So the Stonier company employed the Stuart glassworks to make the glasses & etch them with the Stonier =S= mark? And they then went off voyaging around the world on boats? It was also mentioned that these may have been sold on board as souvenirs. The fact that I have found 6 of these all together might substantiate this.
I have a few questions about them. Does anyone know a vague age? Are we talking 20s, 30s, 40s or more modern? Would the pattern give me a clue of the age? And what kind of glasses are they? They are pretty large, I've photographed one next to a coke can for size comparison. You'd get a big glass of wine in there, so maybe they are water goblets?
Anyhow, I'm very pleased with them. Now have just got to get rid of other stuff to make room for them!
