The engraved inscription: AUGUSTE BONNEVILLE PARIS drives me crazy, I find it beautiful, even better than Lot's. It was the era in which all brands were engraved; only starting in the 1930s did manufacturers' logos begin to be stamped in France. Returning to this flute, we are faced with a beautiful and well-preserved Bonneville, dating back to the early 1900s as its number is 4331. The case is original but needs to be overhauled. The flute is complete, the action is in working order but it needs to be overhauled and tamped. Please feel free to ask for  more info and pictures.
