Good afternoon everyone. I recently managed to acquire a roll film holder for my Voigtlander Avus. It's in relatively decent shape, mostly needing cleaning. My question is concerning this papery cloth material surrounding the rollers. Over the last 70-80 years, it's become rather dry and scratchy. Since it has the potential to come into contact with the emulsion side of the film, I've decided that it needs to go. Here you can see that one piece has already fallen out. Notice how it maintains its shape nicely. So, do I need to replace this stuff or just do away with it altogether? There are some seals (black string type) in the grooves where the two halves come together that seem to be in pretty good shape. I may or may not end up replacing them. This leaves the only real potential for a leak coming from around the hole where the turning key comes out. I've got some small O-rings that should be the right size to take care of that. What do you guys think? Would you replace it? If so, with what, felt?
