Antique Kitchen Scale - Restoration

Restoration of the old kitchen scales.
I have had kitchen scales in my collection for a long time and they need to be restored.
What do you say?
Kitchen scales are devices respectively. apparatus designed to measure mass by gravity. They work on different physical principles. Weighing is one of the oldest and most widespread measurement procedures.

Kitchen scales operate on the principle of a two-arm lever (rocker arm) with equal length arms. At the end of the arms there are bowls, one on the weighing object and the other on the weight. In the middle of the lever is a vertical tongue that allows you to accurately read when both sides are in balance. The isosceles lever balance varies according to the range of weights they are designed for ("weighing"), sensitivity, accuracy and the like. We distinguish analytical, pharmaceutical, kitchen scales, etc.

Accuracy and sensitivity of the scales requires that the lever move as freely as possible without friction, so it is usually stored on blades, sometimes even agate and the like. Sensitive scales have a locking device that allows the lever to be lifted from the cutting edges and immobilized. More sophisticated weighing is done in a closed box to avoid the effects of air currents. The isosceles lever balance is simple and very responsive with a well-designed lever suspension; the disadvantage is the sensitivity to shocks and the need for a set of weights.

The isosceles scales belong to the oldest ones, and very precious stones for gems have been known since prehistoric times. The isosceles scales are also a symbol of justice and already in ancient Egyptian reliefs there is a motif of weighing souls after death, very widespread in the High Middle Ages in Europe. In neighboring pictures, Egyptian Anubis weighs the heart of the deceased, and Archangel Michael weighs the souls given by the other angel and defends them against the devils. (Wikipedia source)
