Yes to old French touring bikes. Ahhh I feel better now, having come out of hiding. So, what can I learn from the serial numbers on this Motobecane Grand Touring:
0780 July 1980?
5556505
These are the stamped numbers, but the shell has 3109 cast into each side, perpendicular to these numbers and contained within an oval.
