I have a Nikor adjustable tank for sheet film in my basement. It consists of an adjustable spiral cage that can be set from approx. 4 inches to 2 1/4 inches. I never used it, but I'm sure my Dad did for his 2 1/4, 3 1/4 speed graphic film. Appears that the film is slid into the sprirals, and a steel band is wrapped around the cage to secure it, and then the cage is placed in the tank, and processed normaly. If anyone has use for it, I could certainly use a few extra bucks. PM me and we can work something out.
