This would suggest to be that the abrasion occurred before the film was developed. Physically stressing the film can lead to developable marks. The most common version of these are crimp marks, seen when you fold the film too tightly to get into the reels. These are not, however crimp marks but seem to be the result of an abrasion event which ended in removing some emulsion at the end of the streaks, hence the black marks alluded to by Eric Nelson.
