What is pitch on an electric typewriter?
The first writing machine was in 1714 and in 1829 the typographer was made. In 1868 Sholes made the typewriter and in 1872 Edison makes the first electric typewriter . The idea of the typewriter began with the development of moveable type in Germany in 1434. So, it really didn't replace anything, but was a further development.
Smith Corona no longer produces typewriters. They have not produced typewriters for over ten years. Unfortunately, the likelihood of there still being a Smith Corona typewriter that has never been used before is very slim. There is nowhere that one can purchase a brand new Smith Corona Electric Typewriter as museums don't sell their items.
