At first sight I also thought of Flamenco - a whole lot of goodies were made in that range - vases of various shapes and sizes, bowls, paperweights, ringstands, perfume bottles, clocks - which is likely why so many people remember that design. BUT - in none of my catalogues (I don't have a complete set, but a fair selection) I find this vase shape for Flamenco.
Being a paperweight person I was much less familiar with the Oban range (no paperweights there) - but the design shows some similarity - and Oban includes vases of your shape: I second Christine's attribution.
