Regarding "Record du Monde"; I see this on many Peugeots, but don't recall seeing it on Gitanes. Many of the early seventies Gitanes say "Service Course" on the top tube. The early seventies models with the foil decals(stickers really) have the model name on a little foil sticker just behind the shifters on the down tube. Can't speak for the later models as I'm not familiar with them.

I concur with Dirtdrop as I also have an early seventies PX-10. If you put the two bikes side by side you can see that the PX-10 has slightly steeper angles. I also prefer the feel of my TdF to my PX-10. Come to think of it, I like it better than my '71 Paramount P15 even though the Paramount cost me 3 times as much as the TdF.
