"Colrout crankset for Campagnolo chainwheel "

"This strange device was invented by a Polish engineer and presented at the Paris show in 1983. Specially designed for maximizing the leverage and using the old Campagnolo 144 mm boltcircle. The set has only been used once or twice. An original brochure from the manufacturer in Argentan, Normandy, France is included. Very rare. "

So, how does it work? And more importantly - does it work?
