Cumbres snow shed

Hi, this is my first post here. I have enjoyed this board for some time.

I am modeling Cumbres on my HOn3 layout. I want to build the snow shed on the wye. I am trying to find plans of it, but I am having trouble locating any. Would anyone have a extra copy of the August 1973 Railroad Modeler magazine, that I could purchase or get copy of? From what I here, there is plans in this issue.

I also tryed to get a copy of Maxwell's plans from the Colorado Railroad Museum, but also, to no avail. Does anyone know where I could locate a copy?

Finally, are there any photos out there that show the snow shed from multiple angles. It seems that the snow shed was not photographed very much.

Sorry for the long winded post. I do appreciate this board. Any help would be very helpful.

Thanks,

Scott
