Thanks.
I have you exact same vase as yours somewhere and have always wondered which factory it belonged to.
Looking at the 1999 Chribska catalogue, I can't seem to see a connecting bridge either in those designs.
Unfortunately, the photos have disappeared in the below thread, although the poster mentions a connecting bridge on the vase, which Jindrich believed was Chribska.
