The other end of the device has a cord coming out of it. The top of the case has three glass attachments that would have attached to the tapered end of the device. Enclosed with this object are a paper pamphlet titled: "How To Use High Frequency Violet Ray" by L. D. Smith, M.D. and the operating instructions for the device.
