Is that really a 5 microamp meter, or actually just a meter with a 5
microamp FSD scale?
It's real. :-)

And a real beauty it is.

What is the internal resistance, AKA how much uWatt does it need?
And how does that compare against 'normal' instruments?

I noticed that e.g. the same type of relay always need the same coil power
regardless the voltage.
