A full story for this subject - I remembered to take photographs with my newly serviced camera while doing it. The plan is to weather it in a used but serviced condition, working from a photograph in a book from my reference library.
I'll be using a selection of materials from my usual stock and will hopefully remember to introduce them as the steps progress. Being a small engine it sits quite comfortably on the painting turntable.
Are you sitting comfortably? Then I'll begin . . . . . . .
What might we use a Sharpie for?
