Submerged vases with crimped ribs

This leads on from my last - in the clear, smaller vases, the asymmetrical application of the submerged colour can be better seen.
All have the same crimped appearance (although I think it was part of the mould) to the ribs, rather like the dorsal fin of some fish.
They are 20.5 and 37cm tall.
The two hallmarks are JHWorrall and Sons Ltd (1908) and David Loebl (1911).
Again, I would like them all to be Kralik, but hesitate.
