Interesting Bass and beautiful wood. I have not seen any other Jacquet Basses that look like that. Most have been Gamba shape and one I have seen on-line in the UK is slightly different but not quite like yours either.
Here it is;
Most French Basses do not have an upper angle bend. That is more of an Italian thing as far back as Maggini and d'Salo. It has been copied and used in England and Germany as well but rare on French Basses.
