测量师 - 1850-1900 - 義大利 - Boffa Virginio

antiqued Italian graduated surveyor’s cross, also known as a pantometer, manufactured by Boffa Virginio of Turin, circa 1890–1920.

This professional surveying instrument was used by land surveyors and engineers to establish alignments and measure horizontal angles in the field. It consists of two coaxial cylindrical sections made of solid brass. The rotating upper section features sighting slots, while the central silver-coloured band carries a finely engraved graduated scale.

The instrument is accompanied by its original fitted wooden carrying case, bearing the partially faded maker’s stamp:

“BOFFA VIRGINIO – Costruttore”

The instrument displays an attractive original patina, oxidation, scratches and signs of professional use consistent with its age. The wooden case also shows normal wear, marks and minor imperfections. The brass has not been recently polished.

The rotating mechanism and adjustment components move, but the instrument has not been professionally calibrated or tested for surveying accuracy. It is therefore offered as an antique scientific and technical collector’s item.

The tripod or surveying pole is not included.
