This weight is displayed both in front of the operator and on the part of the customer who can verify the truthfulness of the weight obtained through a small window obtained in the metal covering placed around the roller itself. The Standard Computing Scale model 155 weighs a total of 38 kilograms and has a maximum capacity of 20 kg. Normalmemte was painted in gold and red and the metal parts were originally nickel-plated. Being produced mainly for the American market, the weighing was carried out in ounces.
