These are very old (1920's) wooden two sided film holders. I have used these with my Nagaoka on occasion for ortho film and they seem light tight. One is an Eastman #1, one is an Ansco, and the other is marked Eastman Portrait Film. The hinge tapes are in decent condition, some of the slides are missing the pull handle but work just fine.
