FTW, I know very very little about French componentry (I did my bachelor in Campagnolo

), but I think that is the Svelto RD:
SO I suspect the FD will match:
Was there a jubilee FD? The CR site does not show one. In anycase, I know that there is a model of huret FD that came with and without the "hood" which is shown in the above photo. That is the funny looking protrusion from the front of the cage. I am not saying it is the svelto that is the valuable one. I have no idea what model it is, I just know there is a huret FD, model unknown to me, that is quite valuable if it is the early version without the "hood".
