They made a lot of socketed meters, in a few sizes. (I have voltage, Direct Current, RF current (both hot-wire and thermocouple varieties existed) and an AC voltmeter marked 400 c/s (presumably for aircraft use).
That meter pictured is Naval, from the A.P. (Admiralty Pattern) part number. It's also extremely sensitive, and probably out of test equipment rather than a radio set.
