The seller has listed it as a
Huret Allvit rear derailleur, which it appears to be but the insert in the package has a line drawing on one side and the model number on the other for the
Huret 700 front derialleur.
Kudos to
Trevtassie for recognizing the
staples as the real treasure in the auction...
