Water Screw Mechanism Study

An open, aged manuscript displays a detailed pen-and-ink study of a mechanical propeller mounted on a central axle. The drawing features a large, segmented circular blade, a pair of interlocking gears in the upper right, and a single feathered wing in the lower left. Sepia and beige tones dominate the parchment, which is framed by a dark background, creating a scholarly and antique mood.
