NOTE: Sid Lethbridge - There is a possibility they are Campbell, Jones who did make a goblet in their Pearl aka Dewdrop with Star but didn't leave us a catalogue image. The colour suggests later as does the versions with the optic. Riverside made a No. 21 goblet which is a definite candidate but the number of rows in the catalogue cut doesn't match with the real world goblets. Perhaps the artist got tired of drawing little circles or the mouldmaker used a smaller punch tool and ended up with more rows of beads.
