Probably still a handheld brick with the big selector switch, but instead of that LCD you’d have seen a large moving-coil meter with a selection of scales for the different ranges. It would have ...

As [MrWunderbar] admits, the dancing needles of moving-coil meters lend hipster cred to ... on how to measure the internal resistance of the meter and determine a proper series resistor.

Frequency cannot be measured with an analog meter multimeter, because the moving coil construction of the analog multimeter meter is suited only for determining quantities by application of Ohm's Law.
