Not sure if this is of much help Tmar...?
Hope my Moto will have some significant value for your database? It was not meant to be a C&V restoration at the time, but a desire to make it into my own version of a 'Team Champion' that was out of my reach when I was younger. I have posted this bike here a few times.
I bought this Motobecane Grand Record as a 'frame only' from a Motobecane Dealer in the late 70's & built it up on my own. Best I've come up with is that it's a '74 model. The owner, Pierre Cuisinot(sp) owned & operated Velo-Club Bikes in Belmont CA. He was a former French racer. The frame was hanging on the wall in his shop & I knew right away...I wanted it. Took my time gathering Campy parts for the build w/ a goal to build it up w/ a SR cmpnt group. I haven't really done too much since other than replace the Cinelli saddle w/ a Vetta , Brake Hoods & put on clipless Look pedals
(have orig SR Campy pedals w/ Binda Straps).
I used mostly Campy parts except for the Edco Competition Headset, Modolo Anatomic Hoods. Stronglight Titanium BB Spindle. Bar & stem are Cinelli 1R, Old Crest 66-40 Bars, Leather stitched bar wrap. Campy Drop-bolt on rear brake. Silca Impero pump & Avocet 30 cyclometer.
Serial #'s are a bit blurred but best I came up w/ are
6717 rear dropout &
38984815 on BB shell. No other #'s on bike. Some of my fancy drill work on the shell, but hey, I was young! It really made the bike faster...lol! In doing it, the drill bit got jammed in there, broke & i could not get it out. I had to bring it back into Pierre's shop for help. You should've seen the look on his face. Plus, I did not know about Swiss BB threads either. I had it tightened it beyond belief trying to loosen it by going in the wrong direction. He had a helluva time getting it back out...doh.
Wheels: Campy Hubs, Mavic GP4 32h rims/DT DB spokes/Vittoria CG-CX Corsa tubulars. Pierre also built the wheels, plus another heavier set w/ Mavic MA2 36h rims.
