It has no trailed rim, but does have the filigrana and a fairly different colour with the pale ochre and white spirals, so I just wondered whether this might help id your vase? There is a clichy rose from a paperweight in that book, that seems to be the same colours of the ochre and white if that helps at all.
Ivo, looking again at the few vases in the Cristallerie Clichy book online (not many viewable though), the bottom of your vase and the foot look different to those even though they seem to have a similar shape - obviously they aren't the only ones Clichy made, but just an observation that struck me whilst looking at them again.
Just found this thread again as I've bought a small quite different shaped jug to add to the list in plain opaline with red trailed rim and have been trying to id it.
