I thought you said :
"Where the variac dial and meter was reading 120". I interpreted this that the Variac has its own meter, and both the dial (the graphics around the knob) and the meter (built-in) were showing the same voltage, and then you used the Fluke which showed 130V istead.
So the built-in meter is in agreement with the dial, which is strange...though it might be that the meter was wrong all along and then the dial was calibrated using that meter....but then these dials are not calibrated on case-by-case basis; I think they are mass-produced.
In any case, the dial is never too accurate. However the meter is supposed to be reasonably accurate.
