Mine is 60 cm to top, so about 58 cm square c-c; I think Gitane is French for "Forget how it looks, focus on how it rides!" I always wanted but never scored one with the willow-leaf stay caps, mine have always been the swaged-over variety. Francophile's orange TdF is lovely and were it mine I would clean and scrub everything, replace the consumables and fit a good Ideale or Brooks saddle and call it done. Maybe fine a nicer set of Simplex Competition dt shifters, but that's it!
[MENTION=413240]francophile[/MENTION], thanks for the offer, but the mismatched Zeus locknut has grown on me. I wonder if the previous owner fitted it specifically so it would clear a non-French stem. At any rate, it works, and I am happy with it.

Somewhere I recall reading that TdFs are found with three different fork bends/rakes, though how gospel that statement is I couldn't say. You can see the difference between my green '71 and Francophile's orange one, though - the bend on his starts higher up and looks like a bigger radius than mine.
