Scale - Steel, Iron, Brass - Laboratory balance

It is a scientific or educational equal-arm balance, dating from the late 19th century to the early 20th century, used for precision measurements in laboratory or school settings. The structure is made of metal, with a heavy circular base in cast iron or painted iron that ensures stability, a turned central column, and a horizontal brass arm, probably graduated, equipped with fine adjustment systems. The lower curved arches and suspension hooks are made of metal, partly in brass or blued steel. The surfaces show a patina consistent with the age of the instrument, which retains a sober and elegant appearance typical of historic precision balances.
