1960's 70's Australian Lab Test Equipment - Current Source

This box reeks of Australian history, custom built for Sydney University Physics Lab use in a nice solid diecast box with that oh so common baked enamel finish.

The central element, the large meter is a classic Master Instruments (made here in Sydney once upon a time)

Not sure but I think the meter casing is bakelite material, not plastic
