Seller: bwam (4,482) 100%, Location: Pulaski, Tennessee, Ships to: US, Item: 283627838112 This is an ELECTREAT Medical Instrument. Quack, Quack. It supposedly removes all your pain with a mild electrical current. It works on 2 D cell batteries, not included. I tried it and it definitely gave me a mild shock. Included with the ELECTREAT is an internal electrode, attaching cords and instruction manual. The only date I could find in the manual is 1923 which was in one of the testimonials. The bottom of the box is OK, but the top is in poor condition. Condition: It seems to be working as it should.
