Chama Coal Tipple

I am doing a preservation plan for the Chama coal tipple for the Frineds of the Cumbres and Toltec Scenic RR. I am searching for any photos that anyone might have of it from throughout its history. Sources to search for photos would also be helpful. I am seeking at least one photo from each decade since it was built in the 1920s to document its history. I am an historic architect, and to a lesser extent rail fan (primarily standard guage), so I may not know some of the standard sources for such information. I do have the plans from the Maxwell Collection. Also, any written data that anyone is aware of would be of great help.
