Self-Indicating Letter Scale With Brass Pan. This is a Continental scale cast in iron and brass made probably during the 30’s. It consists of one flat pan for the load on the short arm of a lever and a heavy counterpoise on the long arm. Once the letter is in position, the counterpoise swings upwards to balance the load and an indicator points to the scale, giving the weight in units of Grams. The indicating scale shows graduation range from 0 to 150 gram. The scale is 24 cm (10 inches) high and is in overall good condition. |
