I had this case as a travelling library when I worked as a field service engineer during the 1980's and 90's, it was used to store and transfer all my technical manuals. It has not been abused and is in very good sound, clean order.
The divider within it is not fixed and can easily be removed to store / carry larger items. Constructed from some man made fibre sheeting wrapped over a wire frame and fixed together with I assume, rivet and glue.
Please see all photos, more can be added if you want to see a specific part.
Size is 23" x 15" and height is 9", there are 11 divisions of approx 2"
Smoke free, pet free home.
Thanks for looking and happy bidding.
