15 vintage bowling pins on nylon lifting cords

Size: – low diameter: 9 cm. – height: 40 cm. – weight: 1.70 kg. These bowling pins come from an old motorized mechanism used to put back in place the bowling pins shot with each ball throw. The keels are held by very strong nylon cords. At each passage of balls, detected by a photo cell and after delaying, the lifting motor raises the keels in the stabilizers and lowers them to their initial location.
