A few of us have been working on this great debate for some time now. For the most part, with some exceptions, the manufactures kept getting it wrong, …..looking for answers, we decided to dive in deep, and see what we could come up with for ourselves…..My DuPont rep loves these little treasure hunts I task him to do, and he ran with this ball too,….in a nut shell, no formula exists for the factory lacquer finish used on the locomotive, but he was able to produce the formula used on the cars which is an AE ( acrylic enamel ) formula,….Now, take what I’m showing y’all with a grain of salt, …..to be sure, the original AE formula had lead based pigments, and is in a synthetic enamel coding, for modeling purposes, we have to convert that formula to a urethane product ( Chromapramier by DuPont ) …..we feel the shade of gray should be a medium dark gray, with just a tinge of brown….the formula we came up with based on research, not eyeball match, is pretty much dead spot on with the Smithsonian Dreyfus, & the TMCC Dreyfus, ( 6-28084 ) …..
