I don't know if there are any markings on the hub to tell you, but having a set of thread pitch gauges can be helpful in many cases, as well as a digital caliper. And these aren't expensive, like $10-$15 for the calipers and probably less for a set of the thread gauges (mine were included in a tap and die set). I use both of these tools extensively on my bikes.

IDK but mine takes a standard FW, not French. Check if the FW side bearing is exposed. If it is, it is a 550.

Oh boy do those look familiar. I'm not sure if the link/thread will help you with your original post but there is a lot of good info about those hubs in it.
And by the way, +1 to what Ex Pres says. Buy a cheap set at Harbor Freight, if you have one in your area.

I have often seen Mavic hubs (500,501,550 etc) with French threads offered on ebay. Mostly see English threading though.

type questions about components (reminds
me of Jeopardy), but one of the more
interesting mechanical tidbits I've picked up
in the last couple of years is that:
Freewheels and rear hubs generally use
the same threading and diameters as
bottom brackets.
the same threading and diameters as
bottom brackets.
was unable to figure this out by myself, but there
you have it.
This means if you have a RH threaded BB cup of known
standard, you can use it to check the threading fit of a
freewheel. (I have done this and it works.)
And in theory (I have not yet tried this, so if you do
and it screws something up, it was not me who told
you to do it
) you should be able to CAREFULLYtry out the threading on your hub with the axle
removed, for fit with a known standard of BB.
On the RH threaded side, of course.
IT"S AN ALLOY HUB (soft)--It's a STEEL BB shell(hard)
Probably preferable would be to try a couple of known
standard freewheels -- but by now I think you have
the concept, which is do this carefully.
Respectfully,
Mike Larmer

Well, the interestring thing about the specs I posted if that they are in English and French language, so the catalog would appear to have been intended for the French domestic market too. You'd think that they would list French thread options for the French market, if they were available. Of course, they could have dropped the option earlier.
