Nothing sad about flicking or pinging your glass - a lot of us do the same and, as you say, the sound is wonderful - just don't flick too hard

These have a modern look to me, and unless someone recognizes this particular design, then you may never know the the maker or pattern name. You don't give your location, which may be a hindrance to help, but the shape of these certainly entitles them to be called sundae glasses, although the foot does seem a tad smaller than usual, perhaps. I can only suggest you try the one of the replacement glass suppliers (on the internet) - it's possible you might stumble on the pattern.

I take it you have looked very carefully all over these for some backstamp or mark - sometimes they can be very difficult to see.
