This meter is a genuine antique built by Supreme Instruments which started in a garage in Greenwood Mississippi, Mississippi in 1926 and was bought by Hickok, inc. in 1956. Note the scale appears to be inked in by hand. I have tested the meter by applying 5.1 DC Volts with 5,000 and 10,000ohms in series observing full scale and half-scale deflection as indicated in photographs. Obviously the meter needs outside circuitry to calibrate to the existing scale.
