I am doing some work under my 34 Austin Ruby and under the black paint that has been painted on a few years ago the colour looks like a creamy white.
Is that the orginal colour for the diff, chassis front axle etc or has it been painted again sometime in its life.

Original should be black, some military vehicles have a white diff casing to be seen in the dark. Could this be a military Ruby? Or maybe painted white for the blackout in the 2nd world war.

Sorry, what I meant to suggest but made a b*lls up of was that perhaps the axle has been previously fitted to a military Opal, where with the higher ride height the diff would be visible from the rear.
