[Leica] Need help with technical problem

[benedenia at gmail.com (Marty Deveney)]

This is a common artifact of the poor storage properties of this film,
caused largely by rapid failure of the restrainers in the emulsion and
an inadequate antihalation layer on the rear surface of the film.  In
my 120 cameras it also almost universally comes apart at the end of
the roll and needs to be unloaded in a dark bag.
