John Thompson asked:
Isn't this just a Huret Svelto?
NOS Huret Jubilee style steel rear derailleur. Item number: 7196905440
+++++++++++++++++++++++++++++++ That is not a Svelto, but I don't know its name. The unit for sale has Allvit-type geometry, with the parallelogram mounted at the bottom end of a long "bar," which lets it more parallel to the FW edge (+/-). The Svelto uses a Campy-style geometry, with the parallelogram swung from near the attachment point. I can scan a Cyclo-Pedia illustration, and take a picture, if it is really important for someone.
Somewhere in the abcesses of my brain there is memory that the earliest Allvits may have looked like this, but don't hold me to it. That might explain the interest.
