I have looked for this, but not sure exactly whether it's simply a vase, or perhaps a Celery, or just a giant sized roemer - it reminded me of a cross between a W/Fs. water jug, and a large drinking glass. Don't think it's British, so feel sure it must be Continental, although haven't found it yet. I'm sure one of the uranium experts will know quite quickly, and my thanks in advance for any help. Height is approaching 8"/200mm - and a fairly heavy amount of wear on the foot (concave and without any pontil mark) - and has good resonance, although this may be partly due to the cavernous interior. Optically moulded, and am assuming mould blown, with the foot attached as a separate part (as with some drinking glasses).
