I am putting together a consist of cars to be painted in Canadian National's 1960's/1970's black, grayish white, red logo scheme. There are videos of maritime region trains mixed streamlined and heavyweight sleepers, diners, and head end cars painted in the modernized color scheme. Some sleepers, baggage, combines still had clerestory roofs. The only car I am unsure of is what appears to be heavyweight diners on these trains.
I'm in need of info on any diners that survived into this paint without the clerestory roof being rebuilt into streamlined roofs. I've exhausted online searches so I turn to the vast knowledge of the OGR members.
