I've seen the ball bearing pulleys on some old (60s-70s) Allvit and
Svelto derailleurs, so if you spot a junker with these you may get lucky.

The Success is essentially a Duopar body with a short, non-articulated pulley cage. It actually pre-dates the Sachs era, but was continued under the Huret-Sachs label for at least a couple years. Here's a picture of my pre-Sachs Success Ti:

That I'm not sure. Perhaps someone here knows of a Huret timeline?
