Getting drawings on this tower is not that easy. This is Boeing's towers not the Governments. The Freedom of Information Act might not apply. I've been in the tower for the Delta II and its kinda old. The (personnel) elevator was scarey to ride because it fit only 2 - 3 small people and the doors wouldn't open that easily. I'll ask my Boeing rep if they are available.
By the way, what are you using for designing the model? Did you come up with your own scale prints? I'm interested in how you are putting it together. Did you decide on a configuration? Which Delta II are you planning on building?
