General Information
The Simplex 102 front derailleur, second in quality only to its older brother, the famous SLJ and, maybe for this reason, often confused with it.  Attractive silver matte finish on the cage, which may or may not bear the engraved Simplex logo.  Often used on high-end Peugeot bikes in the early 80's, and labeled as such.
