[Healeys] finish of gauge housing

[Oudesluys]

The Smiths/Jaeger instrument housings were zinc electroplated and the 
inside was painted white or white and pale blue.
The zinc (re)plating can be done at home as there are several sets 
available running from a battery using a zincsalt solution, electrodes 
and a sponge. I cannot remember the brand.I do not know if they worked 
properly as I never tried them. They were/are used to repair the 
original zinc coat on modern cars after crash repair.
The zinc plating becomes dark gray with age and corrosion.
Some of the older instruments and the clocks had a cast mazac or zinc 
housing.
