I'm modeling 1980, but the following information I've uncovered will probably be most useful to you. PS - if you have any other questions, feel free to ask: most of the research I've done is around the late 70's, early 80's, but I might be able to answer some questions. You also might wanna watch eBay for an OER in your time frame (I've got one from October 1981, it's been an *invaluable* resource), **OR** might I recommend a couple of books: Patrick C. Dorin's "Missouri Pacific Lines Freight Train Services and Equipment" (includes many rolling stock pics, *and* freight equipment in 1956!!!), and Kevin EuDaly's "Missouri Pacific Diesel Power" (self-explanatory, follows each loco through its purchase).
PAINT SCHEME INFO:
Jenks Blue: In 1961, MP abandoned the "Route of the Eagles" blue and gray for a new paint scheme - a solid blue, 3 inch side stripes, two 3 inch-wide chevrons on both the nose and rear, small numbers on the upper center of the long hood, and the buzzsaw decal under both cab windows with sublettering for which sub the engine belong to if not by he parent (i.e. T&P, C&EI, M-I), and a two-digit number that identified the locos's model.
Turbo Eagle: Starting in 1964, the same dark blue started to adorn turbocharged units, but with a large distinct eagle adorning the long hood, its wings fully shaped, and horizontal lines stretching back from these curved wings. "Missouri Pacific" in white in a red circle on the cab, road number in smaller letters on the top of the long hood, above the eagle logo.
Turbocharged locomotives include all GE switchers and road engines, and all 35, 39, 40, 45, 50, 60, 70, 80, and 90 series engine from EMD (the GP15T was also turbocharged, but the GP15 and GP15-1 were not). EMD switchers are normally aspirated.
Flying Eagle Buzz Saw: In 1974 the buzzsaw herald was replaced with the new eagle logo, and a large roadnumber applied to the sides, replacing the large eagle. On some older models, this last step was skipped resulting in the "double eagle" scheme. The 1974 scheme revisions included: the 3-inch stripes and chevrons were changed to 5-inches wide; the turbo-eagles were replaced by large numbers BN-style on all units; and the buzzsaw decal giveway to the eagle-buzzsaw under the cab windows - the first time the new company logo was applied to any MP rail equipment. It wouldn't be until 1978 that this logo would find its way onto the sides of rolling stock. Also, units with the new 1974 treatment often did not receive the white chevrons on the rear face of the long hood.
