The scale is made of decorative cast iron and lacquered brass plate, most of the lacquer are retained. As shown in the above photo, when in use, the orientation of the supporting plate will remain horizontal thanks to the action of the parallelogram four-bar linkage.

    The design of this scale is unique in that the counterweight on the pointer arm of which can be swung to either the upper or the lower position to accommodate the two different weighing ranges printed on the enameled dial. Of which the lower and the upper ranges are, respectively, 0~100g and 0~500g.
