For a Huret #530 Jubilee Frt Derailleur (80 grams weight), I've seen ebay prices go from a low of $15 in fair condition to a high of $40 depending on the condition and the market demand.
A note of caution, there were THREE somewhat similar Jubilee derailleurs according to my 1978 Huret Catalog...
Model 500 for 2 Chainwheels and 28mm diameter seat tube (used on Peugot frames for example)
Model 500 for 2 Chainwheels and 28.6mm seat tube (used on Raleigh Competitions) or
Model 975 for 3 Chainwheels and 28.6mm seat tube (used on Raleigh Competitions or tandems)
I have a working parts Jubilee Frt drailleur, are you seeking a complete assembly or parts?
