Default Restoring WW2 Junction Box - confused?

Hi All

I've just started to take the paint off of a small SBA junction box and at first was greeted by a shiny copper/brass colour. But going deeper into some heavy pitting the colour gives way to silver, I checked and that is true for the whole box.

Is coating a steel box with copper/brass a common practice?

Was it done for corrosion reasons (didn't work)?

Was it done for conductivity/shielding reasons?

I need to 'fill' in the deeply pitted sections or they will look ugly after painting - what is the best method for this (after passivating the rust). I am worried that the filler will just fall or crack out.


Cheers
James
