One of the greatest inventions in photo processing was the Unicolor reversing agitator and corresponding drums in the standard sizes. They all will process sheet film in sizes up to l6x20, Unicolor also made a small rubber separator that fit on the largest groove to separate the negatives when processing multiples. If you can find some of these separators you have it made. To process roll film, a 3,5or 8 reel Paterson tank work just fine. When developing films using a rotary process , you should reduce the developing time by approx 10 to 20 percent. Ihope this information is of some assistance.
