This Smith-Corona Coronamatic 2200 is a sturdy, electric portable typewriter from the mid-1970's, notable for its innovative cartridge ribbon system that allows for quick, easy, and mess-free ribbon changes. They quote less than 3 second ribbon change. The body is aluminum and plastic and it weighs about 20 pounds and features a 12-inch carriage, a, power-driven carriage return, and, a portable carrying case. This particular typewriter is in remarkable shape and everything works perfectly. It comes with a black cartridge and other color, black and correction cartridges are still available online for approximately $15. I will include a printed copy the original user's manual. This particular model was the choice of many prolific 20th century novelists.
