Rare 1950s electrotherapy "Violet Ray" set by Helios made in Germany. Comes in its original suitcase with violet cushion fabric lining, this early medical device is a fascinating piece from the era of experimental electrotherapy. This lot is sold as-is, for display or collection purposes only -- not tested for functionality. A complete and rare example of vintage electro-medical history, ideal for collectors of antique medical instruments or early electrical devices. Please take a good look at the photos, which are an integral part of the description. This lot will be carefully packed, so it will get to its new owner exactly as it should.
