Faint mechanical sketches revealed after restoration
Catalogued as blank before restoration; faint drawings of studded mechanisms and a stepped form now show.
The e-Leo note records this side as invisible before restoration and devoid of any writing or drawings. In the restored image, however, faint sketches emerge: two long horizontal forms fitted with rows of small wheels or bosses across the top (the lower one carrying a hatched, shaded panel), a long diagonal shaft or tube at the right, and a stepped structure seen in profile at the lower centre. No inscription accompanies these drawings.

Horizontal studded mechanisms joined by a looping cord
Across the top of the sheet run two elongated horizontal forms set with rows of small wheels or bosses; the lower one carries a hatched, shaded panel along its length. A looping cord descends from the right end toward the mechanism below. The drawing is very faint and carries no explanatory text.
Stepped structure drawn in profile
At the lower centre a stepped, notched structure is drawn in profile, resembling a flight of steps or a section through a tiered form. Like the rest of the sheet it is rendered in faint line without any inscription.
