Thanks for all the comments...yes, I was guessing that the dropouts are Simplex (a friend suggested this from seeing a photo). But I now recall the seller saying that the frame would take Huret or Campy...so maybe Huret dropouts make more sense. Is the frame a Grand Jubilee or Le Champion? That I don't know for sure. It does have Prugnat type pointed lugs and windowed lugs on the rear brake bridge - are these consistent with those models? I can send pictures if this would help. (From an earlier inquiry, the responses I got suggested that the early Team Champions came with a wide range of configurations since production was relatively small and often custom. But I don't know for certain if this is the case.)
From Jerry's comments, it sounds like a washer might have been used for these kind of modifications.

Another thing that doesn't add up for me is: How did you mount the derailleur before you filed the notch? Filing a Simplex SHOULD be necessary to even bolt the thing on - otherwise the tab on the derailleur that contacts the stop should be hitting solid dropout steel where there needs to be air, preventing it from screwing on. If you forced it, then you probably mooshed (technical term) or broke the derailleur tab off.
Another possibility is that your dropout isn't Simplex, but rather Huret. What made you say Simplex? Does it have Simplex forged into it, or were you guessing? 'Cuz Huret makes more sense, as Motobecane never used Simplex dropouts (on any frame I saw) but they did use Huret, on the Grand Jubilé. Any chance what you have is a Grand Jubilé that someone put Team Champion decals on?
