Do you have any way of reconstructing whether there's any correlation
between the shutter speed and the presence/absence of the band?  I
don't know what it might mean if you could make a correlation, but it
might be a clue.

Might it have been anything external to the camera--like (though I
blush to suggest it) a camera strap falling in front of the lens?  (On
those rare occasions when I abandon SLRs I have a bad habit of
including my own fingers in more frames than I'd like to admit.)

I assume from what you say that you've checked the interior of the
Leica, between lens and shutter, for any foreign object--like a bit of
thread or a pine needle, or...  well, that's literally clutching at
straws.  :)
