Somebody suggested an applause meter.

 

A bull crap meter. Hook it up to a small microphone and amplifier, set it on your desk, and wait....

Unqualified explanation as fodder for bigger brains:

I think it's because a rotary indicator is used to represent a linear force, so there is some trigonometry involved. Also the spring for returning to zero has nonlinear force:displacement ratio so they probably try to pit these two aspects against each other in a way that results in linear deflection but it isn't perfect.

Might indicate it has a diode rectifier, which would make the start of reading very non-linear.

 

I have a few meters like that, except mine are missing the broken glass.

No, it's definitely an iron vane meter; I popped the hood just to see if I could find any manufacturer's ID
