This is one of three very, very, similar documents that are in this collection. The other two describe ‘Le Nouveau Dérailleur JIC Champion Modèle Sport’ and ‘Le Nouveau Dérailleur Super-JIC Modèle Sport’ (note the cunning use by JIC of the words Champion and Super - given that Super Champion was arguably the definitive derailleur brand of the time). All three documents use an identical image and very similar text.
I think that JIC actually manufactured the derailleur (and branded it up for Super-Inax), but I also think that this Super-Inax leaflet is the earliest document of the three - as it has an error in the instructions on the second side that has been corrected by hand. This error is not on the other two, JIC, documents.
