the similarity of this vase to the basic shape and pattern of item 12540 in the catalogue is striking - though there are differences as mentioned by Anne - the absence of a short top rim and, in the catalogue, there appears to be a short foot rim.
However, the same catalogue page also shows another example in this pattern, No. 12449, with a height of 200mm (c. 8 inches).
Unfortunately this shorter model has curved sides, so is not a match, but I mention this because the smaller example does have a top rim and a much smaller foot rim than the larger vase.
Bearing in mind the closeness of the overall appearance, is it possible that some of this pattern were produced in a slightly non-standard design.
I don't see this pattern in Mark Hill's book, and I could be missing it, but don't see a pattern 'name' on the catalogue page.
Looking at Pamela Wessendorf's 'glasspavillon' site, there is another unrelated but vaguely similar vase from Inwald, and here also there are substantial 'lobes' - so Schrotter must have had a thing about such designs.
This is a great looking vase and a v.g. find.
