Storage boxes for 35 mm colour slides (Wansford)

Each box has 100 numbered slots which could be used for storing things other than transparencies. They belonged to my late father and we have transferred all his colour slides to my computer. Good condition despite their age although one is a little faded. Collection from Wansford or I can get them to Walton near Morrison if that is more convenient. Note that the list of contents inside the lid has been written in but a new sheet of paper or card could be stuck over it. See photo.
