The crankset on the bike (which I think is avery basic Stronglight model 100) does not look promising, in terms of it being possibly a higher model bike. Brakes seem to be nutted too, so I'd say that there's a good posibility that the bike is post 1984, HLE framed, entry level bike with maybe a few mods here and there...... What seems to be a "Unicrown" fork for is not favorable either..... Definitely a main line design Peugeot fork though, from the awkward and almost abrupt looking bend at the bottom.....
Better pics please.... for us to make a better assessment....
