If I was a serious Santa Fe modeler I would definitely purchase that publication and some of the others they had listed. I'm more of a "traditional" train guy that sometimes like to add details to available product more to make them mine than for prototypical fidelity. In this instance my "Blue Goose" isn't even a Hudson. Years ago I bought the Williams version, yes I know it's a "J" but I guess I was buying the paint job more than any thing. I read where another forum member slid a Lionel "J" backhead into his Williams "J" and it was a perfect fit so I thought I would dress up mine. Thanks to your information I'll paint the gauges and some of the valves and hit it with a matte clear coat before sliding it in. I may even try the dark green on the interior if I can figure a way not to mess up the beautiful exterior.
As a Santa Fe man would you have heard any stories as to why that engine was painted that way?
