Hi CR folks,
The photo is hard to make out, but it appears to be a Huret Lux. Made in two versions, a long and a short cage. The Huret Lux deraillieurs were catalog items on Rene Herse bikes (as were many other deraillieurs). The lux came out after the Alvit (my guess 1966-1968) and the long cage model was a fine performer. In person, these are highly attractive,with nice chrome details and hardware.
You can see a Huret Lux on the Rene Herse Demontable highlighted in Jan Hein's Vintage Bicycle Quarterly a few issues ago.

\r?\n> That is not a Svelto, but I don't know its name. The unit for sale has
\r?\n> Allvit-type geometry, with the parallelogram mounted at the bottom end of a long
