I just picked up a brand new Huret "Jubilee" Derailleur, still in bag with shifters, cable, clamp on routing and directions. I haven't opened it so I haven't unfolded the directions to see what the model and year are. I can see the following:"10 Vitesses en Le'ger" and "Derailleur Arriere Huret "Jubilee" Ref. 2200". Does anyone know what this is and is it something desirable? I want to give it to a fellow I know in passing, but won't if I'm gunna see it on ebay selling for mega dollars. Any thoughts?
