Bob,
You have an 1982-84, with some mongrel parts. 1981 was the last year Motobecane offered the Team as a Campy equipped bicycle, and in 1982 went to French (almost) equipment. The color offered for the above years (82-84) was Night Blue and the brakes were Weinmann Super Carrera 400's.
Wheelset for the same years was Mavic SSC's with Clement tubulars and the bars/stem were Cinelli (Giro d' Italia; Record #1).
The derailleurs and crankset sound original, but the Team never was "speced" with Helicomatic hubs but rather, Maillard 700 Professional with Maillard 700 course freewheel (also 6spd; 13-18!!!). Pedals were also Maillard 700 with Christophe clips and straps. Saddle was Turbo (white) with a Simplex seat post (alloy), binder bolt and a TA water bottle cage.
Hope this helps.
Even with the "replacement" parts, sounds like a great deal to me!!
