Welcome to our listing and thanks for visiting. After viewing this item, please check our other listings. Here are four Minox slide trays for projectors. Please view ALL of the photographs. There are four slide trays, and each one is in the original box. On each box, it has “Minox” and “Slide Tray For Minomat-Projector”. Each slide is a durable gray plastic and will hold 36 slides. We do not own a Minox Minomat projector, so we cannot test the trays, but they are in excellent condition and are probably unused. Inside each box is a thin paper sheet with an index for thirty-six slides, but the original owner never wrote on these. There are some small tears on the outside of each box, mainly on the tops. Otherwise the boxes are in generally good condition. With these slide trays came two boxes of what we believe are metal mounts for Minox slides. Please see the last two photographs above. The boxes are unmarked, but inside are many unused slide mounts and also some thin glass pieces. The slide mounts may be aluminum, and each one is marked “Minox”. We are unsure how many are in each box- but there may be about a hundred in each box. We looked through many of them and they are in generally excellent condition. We hope the photos above will help those who are interested. We will do our best to answer any questions. Thanks and have a nice day. There will be no exceptions. We hope that we have described our cameras to complete satisfaction. We are not on-line everyday though, so please be patient for the reply. This is to cover costs of boxes and packing material. We do not make any profit from this.
