Faint mechanisms with numbers and fractions (verso)
Two wheels, an inscribed square and cube, and the fractions 1, 1/3, 1/4, 4/4
This verso, invisible before restoration, carries faint pen and pencil work. Two wheels are drawn near the top above a ruled ground line, with lower sketches of mechanisms that the e-Leo catalogue links to a multiple-barrel device and a screw lift. Between them a row reads 1, 1/3, 1/4, 4/4, and small geometric figures of a square and a cube appear in the centre. Much of the drawing is very faint and further untranscribed marks remain.

Wheels and devices in faint pen and pencil
Near the top two wheels — a large spoked one and a smaller one — sit on a ruled ground line, with fainter mechanisms sketched below. The catalogue associates the sheet with a multiple-barrel device and a screw-type lift.
Row of numbers and fractions
Across the middle of the sheet runs a short numerical row reading left to right: 1, 1/3, 1/4, 4/4.
Inscribed square and small cube
In the centre a small square carrying a numeral and a lightly drawn cube appear beside the numerical row, geometric figures set among the faint mechanical sketches.
