To further confuse any restoration issues for early 1970s Peugeot PX-10 owners... Here is an odd scan enlarged from my 1974 Peugeot catalog:

If you look carefully, you'll see what was really an oddly "premature" placement of this Simplex Super LJ front derailleur, on a bike which was not yet being offered with it.
The other photos on the catalog page and the description of the components all indicate the Super Competition front derailleur was STILL being specified for even this "LE" model - Peugeot's top racing bike model available to consumers at the time.
