This Walter Flory advert from August 1967 is the first to feature the Huret Luxe (2100). Since this derailleur does not appear in the Huret 1966 catalogue, this makes 1967 a reasonable guess for the launch date of this derailleur.
The image of the Huret Svelto shown is of a version that had long been superceded. By 1967 the Huret Svelto had plastic-edged pulley wheels and an outer pulley cage with only two 'spring catchers' on it. Walter Flory has form for re-ussiung old images - presumably in an effort to confuse future derailleur historians.
Many thanks to Andy Fraser for lending me this magazine and allowing me to scan it.
