Ed,
Badger’s Model-flex 16-86 MoPac Blue. I have a MoPac Color Drift Control card for Diesel Locomotives and Passenger Train Cars dated April1974. The Badger MoPac blue matches.
Don’t know why Jenk’s blue gets a bad rap. Probably because it replaced the Eagle blue and gray. Having been born around the time of the change I do not recall ever seeing blue and gray equipment. I always liked the simple elegant understated Jenk’s paint scheme.
Agreed as a modeler it is simple to paint. Almost as easy as Penn Central black.
