Rear of Electro Hygiene Sewing Machine
We did a Google search of the words "electro hygiene" and most hits obtained were for electric toothbrushes. However, we did find McCormick's Electro-Hygiene Company in Youngstown, Ohio. The Web Site indicates they have been there since 1964.
Bill Holman tells us that the Electro Hygiene brand name was originally owned and used as a 2nd label by Royal Vacuum Cleaners, and they eventually authorized Julius Toth of Dayton, Ohio to distribute them under this name. During this time, Toth also used the Electro Hygiene name on quite a few generic Japanese sewing machines which he both wholesaled and retailed.
