I checked out the DVD from ghostdepot. The CAD drawing for the Chama tower looks like it's taken from the general plan that I mentioned. If that's what you get when you buy the DVD, you're not going to get the as-built plans for the Chama tower.
The John Maxwell collection is a good source for drawings, but that's where I got the general plans that were labeled as plans for the Chama tower. Turned out that wasn't the case.
Another source is Mike Blazek. He has a great collection of drawings. Form what I've seen they are as-builts. No dimensions on the drawings I got, but he does call out the size of the lumber.
What's working for me is the combination of the general plan and Mike's drawings, in addition to individuals with first hand knowledge (or can walk across the street to see it) like the ones on this board.
