These could be used for adding a front derailleur to a bike equipped with Cambio Corsa or Cambio Paris-Roubaix rear mech, or for adding a front derailleur to a bike which originally only had a braze-on mount for the rear derailleur shift lever (as seen on many city bikes). Could also be used to replace a damaged left braze-on mount... Huret even made one which straddled the right hand braze-on to keep the levers in-line with on-another.
