This galvanometer has been designed for very low current measurement.
Leveling screws for balancing the coil.
Coil with mirror suspended between the long suspension at the upper end and a spring at the lower end.
Suspension and spring are made of special alloy to provide high degree of sensitivity to the movement.
Movement housed in a Bakelite case.
