Sumpter ValleyRy OLC Sawmill at Whitney,OR

I am modeling the Sumpter Valley Railway from Whitney, Oregon to Prairie City, Oregon in Sn3 Scale/gauge. As a part of this I am going to model the Oregon Lumber Company's Sawmill at Whitney. I have taken a fair number of photos of this mill on all sides from 1985 on, but I have only photocopies of two photos of when it was operating that Ron Harr gave me. I also have no old photos of the west side of the mill where the boiler room had to have been located. Thderefore, I have little idea how this side looked when it was operating. I am looking for any and all photos of the mill when it was operating or at least before anypart of it was destroyed. Actually I am looking for any and all photos of Whitney and its surroundings as well as any photos of the SVRy from Whitney to Prairie City. I will greatly appreciate any help you all can give me in this quest!
