G'Day MLU'ers,
I hit one of the fuel tanks with the pressure washer today. I previously reported the inside of both tanks 99.9% rust free (well, the bits I can see, anyway).
As layers of paint came off I noticed 3 colours. The first coat sems to be Olive Drab. Second coat sandy yellow. Top coat dark green. Does this indicate it's history in any way? (Let me guess, assembled in Canada & painted olive. Shipped to Western Desert & painted yellow/sand. Shipped to Aus & painted Green. Too simple??
