I was gifted this old home electrolysis outfit from my uncle 20 someting years ago, he informed me that my great aunt had purchased new a long time ago. enclosed is a letter with dates, the address and company name of where ther outfit came from and full use instructions. I have tried to look up similar units but have had no luch apart from google images show me a newpaper ad for the Marella Company that supplied the outfit. Any information you could give me on this interesting item would be great!
