Mechanical Balance Scale
This is a mechanical balance weighing scale with two pans, where the left side usually holds a bowl for loose goods such as grains, flour, or vegetables, and the right side holds standard iron weights, with a central needle (indicator) showing balance — pointing to the center when both sides are equal — and a frame made of iron or steel, with pans of metal or aluminum.
These scales were widely used in markets, provision stores, and by traders in India until electronic weighing machines became common in the late 20th century, known for their accuracy, durability, and simplicity, with shopkeepers keeping a full set of standard weights (50 g, 100 g, 250 g, 500 g, 1 kg, 2 kg, 5 kg, etc.) alongside the scale; they represent the traditional trade practice of manual weighing, ensuring fair exchange of goods and symbolizing honesty in business, and today are valued as antique commercial tools and reminders of old marketplaces.
