The Big Sky Blue paint diagrams were dated April, 1967. The book GN Color Pictorial, Volume 2 on Page 16 shows a picture of GP30 #3005 in the BSB scheme at Spokane in August 1969. In that photo, the paint appears reasonably fresh so I would assume the unit was probably painted earlier in 1969. I hope this helps.
Jack, regarding that 1967 Directors' Special, it is pictured in the same book on Page 34. Of the 6 car consist behind the heater car, a diner and one GN business car were still in orange and green. The rest of the train was a full-dome lounge car and three more GN business cars. (The last car would be A28, President John Budd's car.) There wasn't a baggage car in the train. I've never seen a baggage car in any other GN director special consist photos, either. FYI.
