Dinshah attuned color wave semaphore or Spectro-Chromes, were machines invented by Colonel Dinshah P. Ghadiali, based on the idea that chemical elements are attuned in color waves. His idea was to shine the colors onto the patient to heal them. The basics are as follows, green was a germicide and muscle builder, violet a cardiac depressor, red hemoglobin builder, and so on. Highly criticized in the 1940's, the machines were discredited by the FDA and in 1951, the FBI entered Dinshah's lab and destroyed all of his machines that he had. This is a rare surviving piece of unique and crazy medical devices. Cable is wrapped with canvas and has a small chip in the plastic of the plug but overall the machine is in good condition. Comes on a stand with wheels and adjustable gears for elevation. Measures 44"T x 17"D x 14.5"W.
