I have three wooden 5x7 film holders. They are all in reasonably nice shape, don't look like beavers have gotten at them or anything. I know that I used one, and there was a light leak with it, but I never retaped it or anything. I have enough plastic holders that I don't need to use wood ones. These look eminently repairable, but are sold as-is. 2 are Kodaks and one is a Hoffman. The one that leaks I marked with tape. They have some paint pen markings on them.
$30 + $6 S&H.
