Thanks for the compliments on these guages. I am really pleased with how they are coming up.
Restoring them is probably overstating what I am doing to them really.
They were all in working condition to start with. They were just very dirty inside and the glass was cloudy. I carefully prized off the bezels pulled out the main assemblies.
Then cleaned the faces, inner body and glass with window wipes and a lint free rag.
Amazing how much brighter they look now.
