"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

"frère meaning brother?"
yes, old/original name of firm was this
referring to Jacques Andre Huret & Roger Henri Huret

"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

"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

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.

"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."
"The first version of the aluminum bar has a long, bulge-formed center section, no knurled rings and a non-anodized, polished finish. The second version has an engraved sleeve like the steel bars, with two rings of knurling at the clamping area and a polished finish till 1965 with the start of the clear anodized finish, then three rings of knurling and finally a single ring of knurling."
"At the Rome Olympics Cino Cinelli introduces the product which will become most strongly associated with the brand’s name: the aluminum 1A stem and its accompanying series of handlebars."

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
