equal-arm balance by Dey & Sons
 

This equal-arm balance is made by Dey & Sons, I suspect from India or maybe Pakistan. On the balance beam is a D&S logo and the company name. The English indication for the weighing range is also on it: Class B to weigh 200g. On the opposite side, probably the same is written in a language I don't know. In the middle of the balance beam there is a round lead mark in which the year 1984 is probably stamped as 84. Whether this is a calibration stamp, I do not know. The balance is mounted on a cabinet with a drawer containing eight brass weights with the TOLA unit of measurement. BULION is also stamped on the weights of 5, 3 and 2 Tola. These three weights have a countersunk hole on the bottom filled with some lead. The smaller weights do not have a recessed hole on the bottom. The remaining weights are 1, ½, ¼, 1/8 and 1/16 Tola.
The value of 1 Tola in India is 11.66 grams. In Pakistan, 1 Tola is 12.5 grams. Weighing my 1 Tola weight on a digital scale results in 11.67 grams, this balance is therefore probably from India.
Below some more images of this equal-arm balance.
