Contrôleur ACDFK Badin type 30 Unfortunately this item is not available anymore.
The Badin ACDFK flight controllers were installed in various French aircraft in the 1930s. They differed from one another based on their type, which varied according to the speed range they could measure. This particular one is a "Type 30" indicating a maximum speed of 360 km/h. It's dated January 1936 and is in excellent condition. This kind of item, especially in such a pristine state, has both decorative value and significant historical resonance, making it appealing to a much broader audience than just instrument panel collectors!
