Description from the seller
Old folding articulated rule for architect/surveyor – 19th century
Old folding and articulated measuring instrument, consisting of two parts, with numerous branches connected to one another by metal rivets.
The different branches feature finely drawn or engraved graduations and scales, with several numerical indications.
This type of instrument was used to perform or transfer measurements, notably in the fields of architecture, surveying, and technical trades.
The rule is made from a natural white material of animal origin, probably worked ivory or bone, not tested and thus indicated with caution. The joints, rivets and tips are metal.
A metal tip also bears an ancient numerical mark, which may correspond to a workshop, fabrication or inspection number.
Estimated period: 19th century.
Old condition with a beautiful patina, traces, small stains and signs of use corresponding to its age. One end of a branch is broken and has a missing piece, clearly visible in the photographs. The joints are present.
Interesting item for a collection of antique scientific and technical instruments, measuring instruments, architecture or surveying.
Materials: natural animal material probably ivory or bone, metal
Era: 19th century
Condition: antique, with signs of use and a broken end.
