Post/letter scale - Cast iron, Steel, Slate - Mechanical letter scale

Early 20th-century mechanical balance scale, likely used for precision weighing in a professional or technical context (e.g. pharmacy, laboratory or postal use).

The scale is made of steel with a black stone base (possibly slate). It features a compact and robust construction with clearly visible mechanical components and engraved measurement markings. The mechanism is intact and moves freely.

The object shows visible signs of age and use, including surface wear and patina consistent with its age, but remains structurally sound.

An authentic industrial object with a strong functional aesthetic.
