Gambrell, Croydon resistance box. Science lab equipment from a school?
"A resistance box or resistor substitution box is a unit containing a number of precision resistors connected to panel terminals or contacts so that a desired resistance value can be obtained by withdrawing plugs (as in a post-office bridge) or by setting multicontact switches, which allow any one of various discrete resistances offered by the box to be dialed in. Usually the resistance is accurate to high precision, ranging from laboratory/calibration grade accuracy of 20 parts per million, to field grade at 1%."

Thanks for that. It was bugging me for ages.

The case doesn't look like it took resistance to well at some time.
