Recently acquired what was advertised as a Gitane Tour De France model but there is nothing on the bike indicating this. It has a Reynolds 531 decal and "Service Course " on the seat tube sticker. Kind of a Franken bike with Simplex shifters and rear dérailleur, Suntour LePree front dérailleur, Dura Ace 52-47 crankset, and Mafac competition centrpull brakes. Wheel set has also been replaced. Looking for thoughts on what would be the original components.
