I just bought a Peugeot from southern France. I guess it from 1975-1980. Can anyone help me identify it? Are there any scans from the original catalog available online?
It seems to be a mid-1970s Peugeot UO8 (@mark in the comments note it may be a same-period AO8) to my eyes, essentially the male version of the 1975 mixte UO18 that I own. All of the components are identical to what I have including the MAFAC brakes and the decals. A google image search confirms:
A good reference website for the UO8/AO8:
Note that if that's the original AVA stem, you should immediately replace it. Google "AVA Peugeot Death Stem" if you want to know why (basically, it has a tendency to er... snap ... while riding).
There are some Peugeot catalogues (mostly in English, some French) from around that era at the Veteran cycle club online library (note they're not in order, but the '76, '78 and '79 catalogues are there).
Your date range seems very reasonable; it's not quite right for a '76--'78 Amateur Champion (decals on forks and downtube don't match) but there's a lot that's similar. You'll have to be careful of non-original components - obviously the bar tape is modern and it's bound to have got through a few drivetrain components in that time.
