This is a Smith Corona Seventy (Corona Seventy) electric typewriter. 

It is made of blue plastic and off-white steel. It contains a black and red ribbon, and types letters at 12 characters per inch. It is approximately 14 inches wide, 12 inches deep, and 6 inches tall, and weighs about 18 pounds. The cord is a little over 7 feet long and ends in a two-prong plug. There is a metal clamp, not original to the typewriter, holding the cord inside where it enters the typewriter (not visible from the outside). There is no case.

It runs on ordinary household current and draws 3/4 amp.

Some minor cosmetic damage, but it works great!
