OK, then, I have taken the leap and progress is satisfying so far.
I am weathering a Lionel JLC Series Norfolk and Western Y6b.
It is rather difficult to find prototype photos that show how these locos weathered.
Of course, most of the photos are black and white and the photography was not always good enough to show the weathering patterns.
The photos show shades of grey which is easy to capture when you weather but I would like some iron oxide in there, too.
I also assume that working locos had very little rust. Perhaps on the couplers and on some of the pipe fittings at the end of the loco's life.
The tender deck would have a little, perhaps and there would be some iron oxide sliding down the sides of the tenders.
The problem is, I cannot find photos of these types of weathering patterns and I would much rather not use my imagination.
If any of you could point me in a good direction, I would much appreciate that.
