Can you identify this bike?

I have no idea of what make it is because when I bought it was painted with a thick black paint. I cleaned it up to the frame, but I was unable to identify any labels. So here is what I know: Vitus frame, aluminum alloy I think, Nervar aluminum cranks, Shimano 600 front and rear derailleur, Suntour cassette, Maillard hubs, Weinmann brakes and brake levers (marked 1982), Shimano Z401 shifters, aluminum seat post, the chain has "France" writen on it.

Thanks
