Just got a new bike that I will be using for commuting. Apparently it was made in a French bike shop called Thévenon Cycles, located in Saint Just Sur Loire according to the decals (it's next to Saint Etienne, which was known as the French capital of bicycles). I found an address and phone number on google but unfortunately the shop is now closed. Besides the decals it doesn't have any other identifying feature or serial number.
According to the previous owner it was originally equipped with a full Shimano 105 group (he replaced quite a few pieces before selling it to me, probably to fit them to his other bikes). The remaining 105 components date it at mid-late 1980 which I think is consistent with the style of the bike (paint job, decals etc.) The main 3 tubes as well as the fork are made of Reynolds 531, that and the 105 group lead me to think it was a mid/high-end bike when it was originally released.
Among the components that have been replaced are the rear derailleur (Huret Challenger II), shifters, brake levers, front hub (Shimano Exage) and rear hub (Joytech). I don't mind all the part swapping except maybe for the rear derailleur. I might swap it back with a Shimano derailleur in order to have indexed shifting (or maybe I'll just get used to friction lol).
Freewheel is a Maillard Course 6-speed, rims are Mavic MA3, stem is an Atax, bars are Guidon Philippe and saddle is a San Marco Rolls Due. I added a set of MKS GR-9 pedals with steel toe clips and, since I'll use it as a commuter, a set of Crud Roadracer fenders.
I'd say the craftsmanship is decent if maybe a bit sloppy in places. I like the cable routing through the top tube (very clean IMO), the cutouts in the lugs, the fastback seat stays and of course the paint job!
After cleaning and tuning everything I took it on a test ride, it fits nicely and rides beautifully (can't say the same about myself though, I'm totally out of shape!). It sure helps that the roads are so much nicer here in France (I was previously living in NYC).
Finally, here are a few pics:
