I worked at a Nishiki/Peugeot dealership from 1972-1974, and I was riding a 1971 American Eagle Semi Pro (Nishiki Competition) at the time.
I remember when the Road Compe was rushed into production, as a tweaked Semi-Pro. The Professional was a refined version of the Road Compe.
Yours is a particularly well-preserved and beautiful specimen.
Brakes would have been DiaCompe clones of Weinmann 999s.

The basic shortcage V rear derailleur and reverse-shift (normal high) front derailleur also were standard. I now use a fancier Cyclone II on one of my road bikes, but frankly the old early 1970s V-GT and V worked just well, and far better than ANY competition from Europe.
Yes, 54-44 / 14-16-18-21-24 Alpine / 1.5-step gearing was stock, with the newfangled gold-colored freewheel. I copied that gearing when I readied my Semi-Pro for the 1972 Los Angeles Double Century, and it worked out OK for me, although I now use 2x6 or more gears now, with a 38/26 or lower bottom end, and I no longer need a 104" top gear.
