There is a French Motobecane catalog from 1976 at Velobase.com where you might possibly find an earlier version of your bike. There were very different models, and many more of them, than were exported to the US, and shown in that catalog. Actually I have learned here that the US importer, Ben Lawee, was largely responsible for the US Motobecane models, maybe that included naming them. I would guess that in DK most if not all the MB bikes could be bought.
