Last week I bargained myself a new in the box early Grand Jubile from a guy that sells used bikes. He had two, I bought both, both are missing their front and rear derailleurs and cranks. There seams to be some difference of opinions on what will fit these frames when it comes to rear derailleurs. Both have Campagnolo branded forged rear dropouts and I was told that both frames are pre-1974. (Several local bike shops who sold Motobecane bikes back in the day both said there were no pre-1974 Motobecane bikes).
Mine also has a glued on aluminum head badge, just a printed M on an aluminum plate. The stem measures 22mm and is branded GB, the handle bars say Made in England on the one end. (The bar tape, small parts, Atom pedals, and saddle are packaged separately. The saddle is padded leather, scripted with the Motobecane 'M' logo.
The wheels are Weinmann, sort of a convex shape, a bit on the wide side, with dimpled spoke holes. The spokes are all marked with an R on the hum end. The hubs are Normandy and dated 03 73, and 04 73. The brakes are Weinmann Center pulls.

All markings on the boxes are french, there is no English anywhere either on the box or manual. Both frames are what I'd call champagne in color, sort of a gold tinted silver color with red painted pin striping and lettering. The head tube is blood read, the frame and fork are tipped in chrome which appears to have been clear coated which makes it sort of dull. The front dropouts are Huret.

All of the older Grand Jubile bikes I see listed all list Huret rear dropouts, both of mine have Campagnolo dropouts. I found a catalog posted online and very little of these bikes match the catalogs from 1974 or 1975. I've yet to see another GJ with this head badge too. The only other pic I found of this head badge is at Velobase.com: http://velobase.com/VeloImages/Headb...7B5B69298.jpeg

I have two matched sets of Cyclone derailleurs new in the box I wish to use, or else I have a pair of new old stock Campagnolo Grand Sport derailleurs I could use on one of these. I've also got both Suntour and Campy bar end shifters to use.
Will these work on the Campy dropouts? I keep getting told that these came with Huret Grand Jubilee derailleurs, which I'm told means I need to stick with a Huret or at least a French rear derailleur? I don't know what these had when new.

Second, what crankset can I use? The bottom bracket and crank axles are Stronglight, 118mm, the BB is French threaded, but keep in mind both are brand new. I do have one Moto scripted crankset made in Japan, it's marked SR on the back side, and its new in the box but is only 165mm. Will I even notice the shorter crank arms? Will this work with the Stronglight cups?

I also have a pair of Stronglight 93 crank sets which I could use, both are 42-52 with 170mm arms, both are super light and look the part but I'm not sure what crank axle they need. The 118 looks like it may work. I keep getting told that these took a Stronglight 49D crankset. The guy that sold them to me didn't strip them, he claimed to have bought them to fix and flip but had concerns about them being all French threaded so he never bothered.
Who ever took the part off the bikes never un-boxed the bikes, both had only a window cut on each side were the parts were removed. The ends of both boxes were still sealed with staples. The boxes are also bigger than the bike boxes I'm used to seeing, they're longer and taller, the bikes were in the box with both wheels attached, the front wheel turned backwards, the bars down on the frame with the stem loose, cardboard padding over the top tube and the bars draped over, and the crank arms tied in place with a box with parts under the bike. The tires were flat, but pumped up and look perfect, the second bike is missing it's wheels, the guy sold them before I made the deal. I also realized that neither bike has it's upright brake levers. You have to drop down low to grab the brakes.
The bar tape is cloth, Veloluxe with rubber plugs, the cables are spiral type with red covering, and the seat post reads Simplex. Both frames have Reynolds 531 decals with the words Construit Avec on top, and 3 tubes Renforces on the bottom. The decal is square in shape, not rectangular like those I see listed for French bikes. Both decals are flaking away.

If these were pre 1974, could they have been bought in France? If so did they spec bikes differently for export than those sold there?
When did Motobecane start making the Grand Jubile?
