Not the type with the lip. Could have been 70mm, but now thinking about it, as the parts are mostly late 70s, my guess is that the bike was overhauled then and the maybe original 74mm BB and Magistroni crank was removed in favor of the square taper.-----
"Georg Fischer, BB surfaces have been faced down to 68mm."
is this one of the sandcast ones with the prominent lip on the drive side?
modification means that one could not fit a SPECTA or Verot bottom bracket assembly without resort to spacer washers
these two firms do not offer spindles for 70mm shells , probably for economy, and accommodate Italian dimension by making the walls of the Italian cups one mm thicker than those of their BSC, CH & metric cups
can come up as a limitation on some Belgian machines constructed with 70mm BSC shells; Flandria for example

Traction Avant... Always frères in the bicycle industry."frère meaning brother?"
yes, old/original name of firm was this
referring to Jacques Andre Huret & Roger Henri Huret
---
I didn't understand it because I thought that Huret had the larger drum..."drum size"
you experience 180 degree of lever travel due to the small drum diameter of these levers; they take more lever travel to move the cable a given amount than other brands
~'74 they joined with the rest of the known universe with regard to drum diameter

"1963, Mod. 1A (A = aluminum) forged aluminum alloy stem and aluminum alloy handlebar production begins; stems and bars have a non-anodized, polished finish till 1965.""Have the laurel and shield/knight crest mod. 64 bars with three knurled rings and 1A "Cinelli Milano" stem."
AFAIK 1A stem not extant at this epoch
'LXIII was approximate launch date for Tecno Tubo Torino but would be a bit grey/iffy IMHO
hence would expect Ambrosio Champion
---
Yes.frame certainly appears Cino inspired
-----
I'm hoping that it's a real Cinelli SC. The replicas or copies don't have the oil port and drain hole and this one has the four digit serial number in the right place. Long wheelbase. The "divers helmet" RD cable stop came around '63. So my estimate is '63-65.-----

WOW, that would be a "whole lotta facing": 3mm from each side
if you have ever used a hand facer you know your arms would probably fall off before you got there...AND you would have had to send your facing cutter out for sharpening as well...
BTW - Windsor/Carabela of Mexico City produced a large number of cycles which sported 68mm Italian thread shells, have had them come through me arbeidstationen

video -
me layman's guess would be that host a genuine Finn; while his last name has only five letters it manages to have three K's
an appropriate name for production company might be "Bad Hairgoods Are Us"

Cino inspired frames -
there were several Italian producers who did blatant Cinelli replicas back in the 1960's
one marque recalled is that of Pinzani
here is an example -
