Just got this Bertin, would appreciate any help in finding out the year and the model.
It has Shimano 600 Derailer and Shimano Gear Handles, 3ttt Stem and handlebars, Ofmega Crank, Weinmann 610 (Vainoueur 999) Brakes.
Can't find any decals for the tubing but maybe the BCM lugs decal is there.
Anyone?

Do they even make a "Ferric Oxide" tubing decal?
Well, once we know what this is it will not be rusty anymore :)
Is this one easier to date? http://picasaweb.google.com/arbez.zebra/Bertin03#

On the first - the Dura Ace EX sticker will pin it down to a few years. The 600 rear derailleur is from the same period, too, I believe. I just don't know the exact dates.
The second I'm making a [generic] guess at mid 80's due to the sloping fork crown, cable braze-ons, and horizontal drops. But I don't know how those features match up with the builder

Early 80's, like 1982 at the latest.
The bike should ride beyond its tubing, sure has suffered outside.
