ERA Quack Diagnostic Instrument

ERA diagnostic instrument by Electronic Research Laboratories, Chicago. The top plate is fitted with a double pole double throw knife switch, a large volt meter, a knob on a rotary potentiometer labeled “low-high”, and two terminals marked “foot” and “electrodes”. One vacuum tube protrudes through the top plate. This instrument is illustrated in the Abrams article in American Artifacts, issue 39. The only reference I can find to the company is an image of the company letterhead in a graphic in the 1924 Scientific American expose of Abrams. The last page of the last installment in the Sept 1924 issue displayed all of the letters received from the ERA practitioners, including this Chicago firm. The oak box is 8” x 16” x 11”.
