Near-blank leaf with faint pencil traces
Invisible before restoration; only a few pencil lines of a mechanism survive
The transcription records that this side of the leaf was invisible before restoration and is largely devoid of writing or drawings, with only a few traces of pencil lines surviving in one section. A pale square at the upper right is chiefly the show-through of the geared digging machine drawn on the recto, and faint mechanical marks appear in the narrow strip at the left and the plank at the foot. The Ambrosiana index links these faint traces to studies of a planing machine and an automatic saw and to a note on a body pulled or pushed, none of which is transcribed here.

Faint pencil traces of a mechanism
Only ghostly pencil lines remain, mostly in the narrow left-hand strip and showing through from the recto. Scholarly indexing associates them with a planing machine and an automatic saw, but nothing on this side is firmly legible.
