List of original components on 1969- early 74 Gitane Foil Decal Tour de France US model 585 bikes:
Stronglight 93 cranks 52/42T - Sugino Mighty Competition Cranks 52/42T on some 1973-74 bikes
Lyotard 460d alloy pedals
Stronglight P3 Headset
Simplex Criterium dérailleurs with chrome plated or polished aluminum down tube shift levers
Mafac Dural Forge, Racer or Competition brakes
Pivo alloy bar and stem - Pivo stem with recessed Allen head expander bolt on some 1973-74 stems
Chrome plated straight steel seatpost
Freccia D'Oro plastic saddle (meaning Golden Arrow)
Normandy high flange Luxe Competition QR hubs - Campagnolo Nuovo Tipo high flange QR hubs after 1971
36H tubular rims - usually Mavic brand - quality level varied.
Cheap sewup tires with tube of Tubasti rim cement or Jantex rim tape
14-24 or 14-26 Atom or Normandy 5 speed freewheel
Toeclips and toe straps usually Cristophe S. M or L appropriate to frame size and white toes traps
down tubes mounted pump on some bikes - quality varied
Frames:
Reynolds 531 tubing with the 3 main tubes butted (head tubes and steerers where cheap non Reynolds material)
Prugnat Type S long point lugs - Bocama Professional medium point lugs after 1972
Nervex Professional fork crowns - Nervex DuBois fork crowns after 1972 with occasional flat top Wagner crowns before 1972
Simplex dropouts in at least 4 variations including 1 style without a derailleur hanger - rarely Campagnolo 1010 dropouts
1/2 chrome plated rear stays, fork blades and fork crown - rare European versions with no chrome or only the forks chromed
Willow leaf shaped brazed on seat stay caps - swagged seat stay tops after 1971
Bridge for brake cable stop brazed on near top of seat stays - before 1972
During this era Gitane measured frame sizes from the center of the bottom bracket to the top of the seat tube which was approximately where the seat tube and top tube intersected.
TdFs were available in the following frame sizes C to T:
50cm, 54cm, 57cm, 60cm, 62cm and 64cm nominal
This worked out to approximately 19 1/2", 21 1/2", 22 1/2", 23 1/2", 24 1/2" & 25 1/2" (very nominal)
There were occasional odd ball size frames, for example I have an early 1974 Foil Decals bike with about a 61cm frame - 24"!
Gitane adopted the classic Mylar Foil Decals about 1968. According to this 1968 price list from Mel Pinto Imports, the US Gitane importer/distributor in those days, Foil Decal TdFs may not have been available in the US until February, 1969.
A few early Foil Decal TdFs had Mylar silver foil inlays in the head tube area behind the Gitane head tube badge decal.
Note, only the 3 main tubes were butted Reynolds 531 tubing on the European models TdFs. The forks and stays were less expensive tubing. Only the forks were chrome plated on those bikes. The rear triangle was painted. They came Simplex dropouts with Simplex Criterium derailleurs or Huret Alvit or Svelto derailleurs with Huret dropouts.
The above items are guesstimates based on my experiences and research. Catalog specifications were subject to change on a whim or due to availability and shortage issues during the US Bike Boom era.
The 1970 Gitane US catalog was used until early 1974.

Did you change the stem? That style of Pivo stem came with a recessed expander bolt was only made for 1 or 2 years. They were much better quality the rough cast Pivo stems used during the early bike boom.
White paint is very easy to touch up. I use automotive touch-up paint tubes. See pictures below.
