Inv. 9094
Interpretation by Luigi Tursini, 1953

"This needs to look like one of the three iron screws of the work at Santa Liberata. Form of plaster and casting of wax"

Keel-breaching device, intended to be operated directly by the assault troops, primarily the divers. The U-shaped clamp is combined with a large central screw.The two branches of the U are attached to two non-contiguous boards of the ship’s hull. The screw is then screwed into the central board. Once this has been firmly screwed in and fixed, the second crank is actuated: by exerting pressure on the two arms of the device, the hull is breached, provoking the sinking of the ship.

The model is based on the drawing:
