      hmm...this is unusual. Simplex made derailleurs for most of the french (and other countries') bicycle makers but I never heard of a Simplex bike. This lever-shift front derailleur can be found in Peugeot bicycles like this:

      There's a lot of material on Simplex here:

      And also an article from Wikipedia on Lucien Charles Hippolyte Juy, the man who invented the Simplex derailleur, but I couldn't find any mention to a bike:

      Finally, not even Sheldon "The Bike God" Brown does list Simplex as a bike maker in his website (check the "Brands" menu):

      You can try this French forum, specialized in vintage french race bikes:

      These guys will probably help you.

      Anyway, this is a good mistery and a nice "vélo de course". Congrats!

      And for the news: apparently Simplex supplied also the fork ends...reading Sheldon Brown's article you can find a clue:

      Dear mcheconi, Thank you for the great work, you've had in order to clarify the matter of the bicycle.
      I could not thank you before because I was with a few drawbacks.

      My very best regards. And thank you again

      Agustin, I am glad I could help. But we still can't tell who made your bicycle. We know for sure that it was not Simplex. The marks shown on the rear fork relate to the fact that Simplex supplied the fork ends with their derailleurs. I believe you will be able to find who made the bike at that french forum. Good luck!
