Added to the collection November 1, 1997, this device is somewhat of a mystery to the Museum of Questionable Medical Devices. A retired physician in Jamestown, ND gave this to Mr. Bob Kenisson in 1980.
This Vibrometer was used for applying "Dr. Garey's System of Massage by Vibratory Motion" according to a silver plate attached to the device. It appears that a motor was once powered a small wheel containing tacks which "plucked" the strings of the banjo-like instrument. The wheel was mounted within the chrome casing shown below.
