I don't see that on ANY Motobecanes,
There is also an "M" in the fork tube, and they used a chromed fork crown cover.
I was not able to find any images of a 1950's Dynamax so if you've got them, I'd love to see them!
Here are a couple of photos of a Dynamx exhibiting the same characteristics as your bicycle. The Huret Allvit rear derailleur with the parallelogram cover puts it into the 1960s while the shift levers with the D-rings place it no earlier that mid-1960s.
Also, your new photos show an EDA BB shell with the newer style logo. I don't know exactly when the change took place but it's different than that seen on Louison Bobet bicycle whch we know are no earlier than late 1950s.
Finally, the head badge style is different than that shown in mid-1950s Dynamax advertisements.
