Tuckervill, have you been able to date any of the components via the vintage Trek website? The crown fork lugs look familiar to what I have on my old beater World bike (apparently made for Schwinn in Taiwan), but the rest of it doesn't look familiar. As others have said, the fact that it has clamps for the cable makes it pre-1980s. It does have DT shifters, so it must be a little more upscale.

Having said that, I don't think it's a Nishiki. Nishikis should have a serial number on the bottom bracket. It's an easy format to date (with the exception of my oddball numbered Nishiki Pro). Nishikis were originally headbadged as American Eagle, certainly as early as 1971. But you should be able to find a number of the bottom bracket if it's a Nishiki.
