See how the TDF has rubber on the shift lever? Ours didn't have rubber on the shift levers, and looked more like the Olympic (or the 3rd bike: Tour de L'Avenir) in this catalog image. I can see the frame of the seat on that Olympic like I remember, but I'm just guessing... been a long time.
One of these in the catalog translates as "suede" seat, which is what we had, a black suede seat/saddle, not sure if it's this catalog that does or not... (not translating it again.)
