Peter Kohler wants to know
> the approximate year when the Huret Jubilee derailleur was
Well since no experts have chimed in I'm gonna go with '73, based on no real evidence other than that's when I seem to remember it... ;)
Also the '74 Raleigh catalog calls it the "New" Huret Jubilee, and we know those catalogs were prepared before the model year debuted.
