You can look at catalogs from Raleigh and Peugeot thru the years and pretty much see what was low, mid, and upper level components.

Interesting though how Rene Herse used Huret Allvit derailleurs for quite awhile. Sticking with French made components.

Once Shimano entered the scene everything went to h, e, double toothpicks. There stuff worked great but lacked in aesthetic appeal.
