Up for sale is a JOBO 2508 4X5 sheet film loader for use with 2509N plastic reels.  The loader is in very good working condition with some general cosmetic wear from age and previous use, but no glaring flaws (full disclosure: I reglued one of the bottom rubber non-skid nubs since it had come loose).  If you've never used one of these loaders before, there are instructional videos online (it's fairly simple to use once you get the hang of it, but you'll likely want to practice with some junk film in daylight until you feel comfortable enough to load in the dark).  In case you also need some 2509N reels, I've also got some of those listed separately (none are included here--just the loader as shown).  Please be sure to fully enlarge the provided photos, and feel free to contact me with any questions you may have.
