Jack Sport motorcycles were built in France using 350 and 500cc JAP engines between 1927 and 1931, sorry I don't know much more. Lovely rare bike, you've got some research to do there!  :)

Hi Davide, the bottom end looks Blackburne but not the rest. Do you have an engine number?

Il y a peu des infos sur moteurs Blackburne, je pense peut etre dans  le club Vintage Motorcycle club [VMCC] il y aura un expert sur Blackburne, certainement.
Bon chance.
