Hello,
The smaller one is 'Imperial' and the larger one 'Madison'. The catalogue images are a bit small and the pattern on your vase is difficult to see. Both models are in the 1956 catalogue, the 'Imperial' appears again in 1966. I don't know how long they were in production for. There is no pattern number that I know of, as they are not cut but pressed glass, the names just refer to the vases as there are no other versions of these models.
