I'm trying to find a model number for this Leeds & Northrup galvanometer
(pics on alt.binaries.schematics.electronics). It works just fine, but is
missing the meter scale. Probably just a printed card located similar to
the piece of paper I'm using here.
I couldn't find one similar to your photos with Google Image search.

Lacking a model number, this is as close as I could get:

The galvanometers that I've seen and owned had a marker at center
scale, and not much else. They're not really made to be a calibrated
measuring device. They just detect current or voltage in either
direction, like a wire over a magnetic compass. You could use a
precision voltage source to calibrate the full scale markers and be
done with it.
