Challenge six of seven is a Class 20 in interim livery of green with full yellow ends. Again I never saw this engine in this condition, but luckily saw it when blue in TOPS. This is another loco in light to medium weathered condition.

I tend to have relatively clean sides of Locos after weathering. The main reason is when picking up Loco with misted weathered sides it is easy to scratch or leave finger marks from oily hands. Some people use cloth gloves for this process, but I have not really gone that way.
