Greetings---

I'm sure somebody knows this off the top of their head----but I would like to know a few things about the history of Stronglight 49D cotterless cranks------

1) When was the Stronglight 49D cotterless introduced, and did it initially say simply "STRONGLIGHT" or "STRONGLIGHT DEPOSE" on the crankarms ovals?

2) If they said simply "STRONGLIGHT" when was "DEPOSE" added?

3) When did Stronglight 49D cranks go from saying "STRONGLIGHT DEPOSE" to "STRONGLIGHT MARQUE DEPOSE?"

I've searched the CR archives and Scott Davis in a July 14/15 2002 post spoke to one part of my question writing, "I think they added Marquee in mid to late 50s."

But I would like a more definite dates to all of the above questions, if possible.

In my particular case I have a set of 175mm 49D "Depose" cranks and I am trying to fix their approximate date for suitability for a late '40s/ early '50s French rando project.

Any info greatly appreciated.

Thanks!
