Unigen Lighting Start Name Plate. This is the original name plate from Unigen.  It was another entity of Merc-O-tronics.  They are blank.  We could stamp the volts, model, amps rpm and serial number if purchasing for replacement. No one else has these plates.  Unigen and Merc-O-tronic have closed their doors after 68 years. New, but Vintage. Any questions feel free to contact me.
