This Charvin invoice from 1953 makes no mention of derailleurs, of 'Le Lautaret' or of 'l'As des As'. This makes it unlike both the earlier Charvin documents and the later ones.

My guess would be that by 1953 Charvin had ceased manufacturing derailleurs. I would further guess that the later documents mention the derailleurs in a fit of nostalgia.
