this pattern appears on every frame, altho, it has a somewhat different form. But very much a pattern, not streaking as one would find with over use of a wetting agent. Or water streaks from a lack of a wetting agent.
I am unable to scan it and send it along but perhaps next week I can have him make a print , scan it for me and then forwarded it along for viewing.

The tank was a Patterson, 8 reel tank. This only occurs on 1 of the 20 rolls of film.

I would think the x-ray exposure whould not have such a specific pattern, but we have not had that problem (yet).
