Near-blank verso with faint mechanical show-through
Catalogued as devoid of writing and drawings before restoration
The catalogue records this verso as invisible before restoration and devoid of writing and drawings. What the image shows is faint offset transferred from the mechanical recto: pale rings, small device parts and the mirrored numeral 122 read through the paper. No text on the leaf itself was transcribed.

Show-through of the mechanical recto
Across the upper sheet ghost images of circular rings and small mechanical elements appear, together with a faint reversed 122. These are offsets of the drawings on the other face rather than marks made on this side. They are too pale to constitute an independent composition.
