Thanks Pip, yes it is the same design. There are quite a few items in Marcus's database with no image associated, I wondered if it was one of those items but I do not have the resources required to pursue this possibility (if they exist).
Looks like you had the same difficulties photographing yours that I did with mine, clear glass is so much more demanding than coloured. The different angles/planes in the vase make it very tricky, I had slightly better results on an overcast day than I did in bright sunshine.
