Adjustable 2509 reel accommodates 2x35mm or 1x 120 roll film or 5"x4" sheet film. In theory it can handle 6 x 5"x4" but general opinion suggests 4 is a better option in practice. This has not got the optional blades which were a modification to ensure more even chemical distribution: again opinion differs on the efficacy of same. A leading authority recommends a 5 minute pre wash of water. This example has magnet securely attached to the base. I cannot explain or remember why the usual branding and capacity info is missing: the info is widely available nowadays on-line.
