Huret Jubilee was a neat derailleur, but its range was rather limited. It was popular for British style time trial setups and other weight-weenie applications.

The other Huret derailleur that worked reasonably well was the Svelto. It's ironic that Huret's best units were the unconventional ones. The abominable Allvit and Luxe were designed for the jockey wheel to follow the taper of the freewheel by mounting the parallelogram upside-down at the bottom of a rigid arm hanging from the dropout.

For the most part, European rear derailleurs from this period were copies of Record and Gran Sport. The only unit that offered a significant performance improvement, the Sun Tour Cyclone, had a patent on its key feature, the slant parallelogram.
