I have a '77 with no cable guides and screwed head badge. I have a '78 with no cable guides and screwed head badge. My wife has a '79 (900) with cable guides and a glued head badge. The '77 is a fastback TX900; doesn't need documents because they only made a few. The '78 came with an original receipt (TX930). Patti's bike was dated from the serial number and we have a reasonably good match on that. On the other hand...Skip's site has many examples from 80 and '81 that don't have cable guides...so patti's bike was a repaint with additional braze-ons or a custom order, I guess. They did some custom orders on various models...
I've gotten to like those cool little cable clamps around the top tube. Do you have additional pictures somewhere?
Maybe we should start an old Trek thread since they're sooo popular.
