I bought this unit from my old employer when he closed down. It worked so well (and without any electricity!) that I used it for my own stock control of electrical goods until we closed down last year. I just photocopied cards and clipped holes and carried on. It is a very heavy unit, hence collection only, unless it is local to us.
Lid is 880mm x 46mm and slides vertically to the back of the unit or it will open as a normal box lid if required.
Height is 770mm and unit is mounted on four castors, I am not sure that all the castors work. Unit showing signs of age.
Last photo shows ‘master’ card I used for photocopies and pile blank photocopies that were left over.
