Motobecane Tour de France Model

I have just added some photos and bits of information on a recently acquired Motobecane Tour De France model frame.  It is a production frame that looks very much like the 1970-72 Bic Team bike frames. but I need more information in order to be able to say whether it is from that era or later.  I do know that Motobecane used the same decal style on later models, but I have not seen them on a later racing frame similar to this.  The jury is out.

Motobecane do not seem to be as well-documented as some other bicycle brands, so I would appreciate any information that anyone can provide – catalogue scans would be especially welcome.  I would be very pleased to receive anything that I can post on this website.
