This is just a rectangular part of an aircraft that changes into the shape of a totem; this is definitely a most interesting item!
It is actually part of the wing of a Fouga Magister where the airbrakes are located. It is a distinctive feature of this aircraft, however, rarely seen as most of the time it is concealed, being retracted in the wing.
This mechanical set is fully functional. The air brakes can easily be taken out of their slots and make the whole unit look like a totem.
It is a decorative piece which can acquire thanks to a small electric motor a slight repetitive even perpetual rotative movement, reminiscent of a kinetic sculpture by Jean Tinguely.
The airbrakes are usually part of the wing and they get destroyed with the wing in which they are affixed. This is why it is a rare piece and it is likely that very few copies of it still exist as stand-alone elements.
