Exactly... hence the name... Grand "Jubile."
The model up was a Grand "Record." And, you guessed it, it had Campagnolo Nuovo Record Shifters, derailleurs, cable guides, etc., and had a Specialites TA crank. The Record also had a 531 fork... which I don't think the Jubile had.
Both bikes are very nice! And you got a good deal. It will make an excellent fixed gear if you want to, because it does not have any braise-ons. My guess is that it is around a 74-75. Early seventies models had a decal as the headbadge and a script "Motobecane" logo on the downtube.
