Near-blank verso, invisible before restoration
No writing or drawing of its own; only faint show-through of the recto's artillery study
An editorial note records that this verso was invisible before restoration and carries no writing or drawings of its own. Across the sheet only a faint bleed-through of the recto's composition is visible. The Ambrosiana's thematic index places the sheet under instruments and machines — mortars in action and gunpowder — matching the artillery study showing through from the other side.

Faint show-through of the recto's artillery composition
This side bears no drawing or text of its own; only ghostly bleed-through lines from the recto cross the central panel. The sheet's scholarly index assigns it to mortars in action and gunpowder, corresponding to the artillery study on the opposite face that shows through here.
