Hi Harry,
Great meeting you in person at York on Friday!
That's very helpful regarding the source of the color. I'm not complaining here, just trying to understand, and it seems I have already learned a few things. When I first sprayed the paint on, it was very bright orange. I should have known it would dry darker. Also, my crane must have really aged over the last 80 years. It was a "played with" train, not boxed up like the Madison Hardware stock.
I like knowing about these things so I can explain when I am asked. I am happy with how it turned out.
George
