Thanks all!
I saw that one but dismissed it because it's round. Silly of me, I know, as I don't suppose anyone else would have done them in the same fan design.
The interesting thing is that my seller said that the bowl was bought by her Mother as part of a set with these vases (below) but the vases are on Pamela's site, in amber variation, under 'unknown' (sorry, I can't seem to link to the vase on Pressglas but it's about three quarters of the way down on 'Vases').
Is it possible for the vases to be Stölzle too? If so, then I can regard them all as a Stölzle set, which would be lovely.
Stu.
