While can't identify the bicycle, I will say that it is almost certainly a re-paint and re-decal. The prime clue is the Huret dropout style, which is pre-1978. The style produced from 1978 onward had an integrated cable stop. It doesn't make sense being a 1980s custom frame from Peugeot's Prestige frame shop. Why would anybody order a custom frame without any of the features that were popular at time (i.e brazed-on shift lever bosses, brazed-on bottle bosses, brazed-on top tube tunnels, bridges and crowns to accommodate recessed brake fittings, etc.)? My overall impression is a mid-1970s, French, mid-range model. Has the OP verified the thread standard, seat tube outer diameter, seat post diameter?
