Darrah Electric Co., Cleveland, OH Metal Plating Rectifier. Model # 500-9-230-3.
A rectifier is an electric device that converts alternate current (AC) to direct current (DC) which flows in only one direction.
This was only used for stripping plating off of antiques. We did mainly polishing and stripping of antiques. We stripped nickel, silver-plating off of many brass and copper pieces. Rectifier comes with all original paperwork.
I've included several pictures to show detail. Please let me know if you need further information or additional pictures.
