I'm pretty sure it's a rebadged Vitus "Carbone"
the vitus version turns up from time to time.
I quote:
"Peugeot offered this bike in it's catalogue from 1982-86. this is one of the first carbon road bikes available. Built up with old Campy Record. Peugeot developed the carbon tubing for use in these lugged bicycles. Peugeot colaborated with Bador (Bador was also working with French tubing company to utlizing the Vitus brand name to build complete frames) and both begin offering carbon bikes under individual brand names. Peugeot offered "Team" edition bikes PY-10 FC under the their brand and the bikes. Bador built "Vitus-branded" bikes utilize "Vitus Duralinox" alloy for the rear triangle and Peugeot carbon for the main tubes."
