Iridescent trio with applied glass and textured bodies

This trio are all linked by dimples, iridescence and rigaree in two cases. The iridescence is violet/grey, gold and gold.
They are all Nouveau shapes and the two new ones (in the clear ground) both had nasty dirt to clean out of all nooks and crannies.
The hallmark on the middle is HP&Ss, London, 1907, with a very beat-up silver collar.
Although comment has been made about silver collars, I think that in the UK they are generally a reliable marker of the latest date a vase might have been made (although I accept that all mine have only recently come into my possession). Until recently, the collars were worth more than the vases in many cases.
The body of the one far left has a pinched middle reminiscent of some Loetz footed vases, although I don't think this a Loetz shape.
They are all 19-19.5cm tall.
