Two mounted fragments: shafted mechanism and domed apparatus
Right-hand device carries the dimensioning figures 144, 24, 40, 40
Two small cut-out fragments are mounted side by side on this sheet. The left fragment (929a, on a blue-grey backing) carries a pen sketch of a mechanism built around a vertical shaft, with a large circular wheel or disc at the lower left; the catalogue records it as bearing no writing. The right fragment (929b, on tan paper) shows a device whose broad ovoid, dome-like body rises on a columnar stem set upon a boxlike base, with red-chalk construction lines, and it is annotated only with the numbers 144, 24, 40 and 40.

Shafted mechanism on the left fragment (929a)
The left scrap shows a mechanism organised around a tall vertical shaft or rod fitted with brackets and cross-pieces. A large circular wheel or disc is drawn at the lower left, suggesting a wheel-driven device. The catalogue notes the fragment bears no writing.
Domed apparatus with dimensioning numbers (929b)
The right scrap depicts an apparatus with a broad ovoid or dome-shaped body raised on a columnar stem and standing on a boxlike base, laid over red-chalk construction lines. The only annotations are the numerals 144, 24, 40 and 40, apparently dimensions or quantities tied to the parts of the device.
