I acquired a Gitane frame I purchased in 1980(likely late 70's vintage) but I'm considering rebuilding back to the configuration I had in 1980 (starting with strip and paint). Frame was identified as a Gitane Grand Tour with Reynolds 531. It has no braze-ons. Looking at photos and on-line descriptions I don't see a frame like this (especially the rear spiderweb dropouts) that fits Gitane. Could be a mid 70's as I purchased just the frame from a local (Des Moines, Iowa) bike shop. Would appreciate thoughts on pedigree of this frame and any advice on rehabbing it.
