The stars look right for 'Startime' but not sure about the base ~ it looks a bit heavier than the stemware, but maybe it would have to be because of the shape of the bowl.
When I have this sort of thing to list, I usually call them grapefruit or sundae dishes, assuming they're the right size. I have three Stuart grapefruit dishes listed at the moment which are not marked as 'Stuart' but I tracked them down by the Rd. Number etched on the base.
Sorry I can't help more, John.
