No idea what model it was, and this was about 6 years ago
so I could be mistaken.

I wonder how consistent this is in the world of hardware?
maybe I'll pop a question on rec.audio.pro."

I built a tube compressor like that, an Altec436c.
The 'gain reduction' meter measures the bias current of the vari-mu 
valve, which is reduced when gain reduction is required.
The meter goes from right to left. (Any other way would require more 
circuitry, so I think it may just be a lucky accident.)

Talking of meters, don't some phase meters often go left *and* right 
from a centre point to show averaged phase difference between the channels?
