I think Bill's on the right track, though the SL doesn't have a film-
type window. David, the most likely source of the light leak is the
cotton cord in the light baffle around the film back, particularly
near the viewfinder eyepiece where there are two holes to access the
grub screws that hold the eyepiece on. Another possible source is
through the viewfinder eyepiece itself if the light baffle on the
floor of the eyepiece hole is loose or missing. This could cause a
light leak even with new cotton baffle seals around the film door.
BTW, Lily cotton company's "Sugar and Cream" brand cotton crochet
yarn (black of course) is perfect for replacing the light baffle seals.
