Actually I just went to find a good example scan for you and realize that this was probably a 15sec exposure. sometimes its very evident like in the example im posting, sometimes its more faint. It also comes and goes, 2-3 clear rolls, then one roll will have it in 2-3 frames. I'd really love to track down the culprit of it. I hope is something a CLA will take care of.
