I relented and bought the glossy Testor black. I guess I'll see if it work to match close enough.
Also to show how much work has progressed so far, I added all the white paint I needed to the engine and tender. Don't worry, I'll be covering the handrails when I spray paint the spots I will be renumbering. Next step is the decals, and I will be contacting LBR to see if they can get the logos and correct-font numbers I need. Needless to say, the white paint makes an ENORMOUS difference.
