The instrument fascia in my Series I was at one time brass plated by a previous owner. Although it looked quite nice for some time after it was done, in the 27 years that I have known this vehicle, the plating has bubbled and peeled, allowing elecrolytic corrosion to take place between the layers of dissimilar metals. I therefore decided to refresh the offending panel.
Here is what it looked like in the vehicle four months ago:
Once dismounted with the instruments removed, you get a better idea of the condition of the panel:
(You can see that the state of the plating was not good.)
Below, a view of the instruments- most of the dirt is on the inside of the glass...
And here is a view of the warning lights disassembled. (I have since scavenged replacement bezels and lenses from a derelict Rover P4):
I took the gauges apart, cleaned the glasses front and back, and cleaned the instrument faces where possible. I stripped the panel of remaining plating, and refinished it with a high-temperature black wrinkle paint. I then stripped and polished the natural brass instrument bezels, and reinstalled everything into the panel. The end result is a very neat looking panel, which is actually an inverse of how it had been the last thirty years or so:
The next step is to reinstall the panel into the fascia, and to rewire where needed.
