Craig,
I believe tha the Colorado Railroad Museum has the Colorado & Northwestern #6 car body. I thought that it was the only C&NW passenger car (body) in preservation.
Another body that they have is the D&RGW Americano tourist sleeper by Pullman.
Both of these cars spent years as outfit cars; so there may not be much Pullman fittings left in the cars. It is worth a look anyway.
The City of Boulder gave the C&NW #30, (2-8-0,Dunkirk) to the museum; so they may have a nice display some day.
I hope the Pullman Library at IRM has some drawings of this series of cars, there wer ten of them.
