Theodolite - Chasselon

chasselon – Optical and precision instrument – Clinometer rule with an optical level – 1940s–1950s chasselon, a French house specialized in optical and precision instruments, offers here a rare antique topographic instrument composed of a long brass rule, painted gray, integrating a precision optical level mounted on an adjustable support with micrometric knobs. This assembly allowed measuring slopes, vertical angles and level differences during surveying, leveling and topographic work. The instrument is accompanied by its original solid-wood case, carefully assembled, serving both as protection and as a transport support. The interior is laid out to accommodate the different elements, and the case retains its period leather strap, attesting to professional field use. for collection ( Rare , Very rare , Authentic , Original , Complete , Collection , Professional , Historical , Period , French manufacture , Ancient scientific instrument , microscope , compass , industrial , compass , sextant , steampunk )
