Joanny Panel is advertising his Chemineau bikes (with some models fitted with Le Chemineau derailleurs on braze-on fittings) and his Chemineau L'Izoard derailleur - which had a clamp on fitting and could be fitted to sny bike. This implies that he was no longer that interested in selling the Le Chemineau derailleur as an after-market product - or as original equipment to be used by other manufacturers.

This low-res, deliberately smudged, scan is from the web site of the excellent Musée d'Art et d'Industrie in St-Étienne.
