3 submerged, graduated buttress vases

There isn't a direct link to my last post, but there is a definite link in plain, modern glass, where there is a focus on the material rather than any artifice to do with surface. The link to post-war production of submerged glass is clear. Unlike the last group, the 3 here are modern. If there was any doubt, the submerged colour is slightly off-key.
The dates of the rims are 1909 (pink) and 1914 (green), the maker Henry Perkins for the rim of the pink.
The heights are all 21cm.
