Cool vintage medical device from the United States is a fascinating piece of history. The Halliwell Shelton Violet Ray Medical Quackery Plasma UV Ozone Ionizer Wand was used for various purposes in the early 20th century, and it remains a sought-after collectible today. Its unique design and functionality make it a must-have for any collector of medical devices or vintage curiosities. Not sure but could be on glass attachment missing. Has one that looks like a rake and stainless like straight attachment. In original box. Not sure either if working properly. Was my grandparents and not sure what it is supposed to do for sure! It does vibrate when plugged. Knob increasing and decreasing that sound/vibration increases and decreases when moving knob. Hubby worked in electrical field and he slid cover off and can see it is sparking inside from one tiny component to another . The comb like piece we inserted in hole but we read it was to light up and it didn’t. But husband has pacemaker and do not want him testing any farther so selling as is no returns for parts only. Any question please ask!
