I think I mentioned this earlier, but my 1973 American Eagle Semi Pro has a Nishiki headbadge (dated via component codes). I attribute this to using up a stock of frames, maybe running out of headbadges first when they transitioned to Nishiki name, I do not know. 1973 Semi Pro is the silver bike (KS 161175), 1974 Competition is the bronze bike (KS 284672). Several minor details are different: wheel hubs, RD, dork disk, and crank.
This was my dream bike back when I was a senior in high school. I didn't have enough $$ back then to buy one, so I was stuck with my 38 pound Schwinn Continental. I might just have to keep one of them.
