I think, iirc, that pieces I have seen id'd as Clichy many times over are in fact Saint-Louis.
The Clichy book shows lots of filigrana pieces and none with this style.
Of course, no resource is finite however I would go against Clichy until there is proof.
I don't know if the pontil mark is right for Clichy either. I seem to remember a conversation about the pontil mark being very small and beautifully neat (Ivo?)
Certainly on the piece I have which is Saint-Louis it is also like that. Not a large polished pontil mark.
But then I'm feeling very contrary at the moment when it comes to something being id'd for many years as from a particular house ... and then finding there is no proof
