A really impressive and massive ruler/beam compass for tracing and dividing signed “Soleil rue de l’Odéon 35 à Paris” built in heavy brass and measuring 122 cm or 45 inches lenght. According with the signature we can date the instrument circa 1820s’-1830s’.
The very large ruler is divided with two scales 0 to 110 cm and 0 to 105cm.
At the back a perpendicular rod with two holes that this dividing instrument was used mounted on a larger and more complexe set.
The beam compass of this size are exceptionnaly rare.
Despite an old polishing and a weakness at your head, good original condition.
