you are certainly most welcome if it helps a bit.

after posting, thought of a couple other points:

a) those long Huret shift levers seemed to end some time in the early 1970's. have never known an exact year. the Huret experts could put a date on it . if the levers are original to the bicycle this could give a "latest it could be" date to your machine. they were part of the "Luxe" gear ensemble.

b) the bottom bracket/chainset is either Agrati or OMG.

c) the original stem and bar set would likely have been a 3TTT Turiste.

d) if the hubs are five-piece steel they may well be Agrati also.

e) plating: note how far gone it is. this is because they applied chrome directly to bare steel, skipping the two necessary intermediate steps. this gives a poor bond. sometimes think of it as "showroom chrome" as this is about as long as it lasts. note how well the chrome on the fork crown cap has held up in comparison; this is because it was done correctly.
