Haven't seen one of these for a while.
Two unusual points: This is test equipment for use by (presumably) professional technicians in electronic engineering. But even in the mid-1960s when I think it was made, the clamp should have been on the sheath. Also, these are the thinnest mains power wires I've ever seen, and the cable is long and clearly original. Nowhere near safe on a 15A circuit. This is why I don't trust qualifications. To be recycled.
