The CNW car was not as extensively modified as the Milwaukee cars. Photos that I have seen (they're in the Morningside CNW V2 Color Guide book) show only 1 panel cut out on each side of the car. They were deployed in pulpwood service.
The CNW Historical Society does offer decals and a diagram for one of these. The Mantua car was recommended as a base for a model. I did one a few years ago.
For purposes of this group, I believe the CNW cars were modified after the date range interest of this group.
