Scale - Steel, Iron, Brass - Pendulum balance

It is a historical equal-arm scientific balance, used for precision measurements in educational or laboratory settings, dating from the late 19th century to the early 20th century. The base and central column are made of painted metal, probably cast iron or iron, to ensure stability and durability. The horizontal arm and curved parts are in brass, while hooks, tensioners, and adjustment components are in steel or blued metal. The set retains an original patina from use and age, highlighting its historical value and the functional elegance typical of scientific instruments of that era.
