There are two adjustments in the back of the gauge. On one of my Stag
voltmeters (which is basically the same movement), one of those adjustments
was so loose that it would move by just laying the gauge on the bench a bit
too hard. I re-staked the rivet just a bit to give it more friction.
The adjustments have slots, but don't really turn. Instead, the slot moves
sideways to change the adjustment. I made up a simple tool to make it
easier to move them. I started with a 1/4" bolt and turned the end on the
lathe, but I think you could make something just as effective from an old
cheap screwdriver and some work with a file.

Yes, I believe most of the gauge rebuilders (Nisonger, Mo-Ma, North
Hollywood, Valley Instrument, etc) will "do" the smaller gauges. But I kind
of like doing myself when I can.
