This beautiful typewriter uses a swinging type-sector shaped like a partial wagon wheel instead of type-bars. The characters are molded onto the outside surface of the swinging-sector, which is rotated into position with the depression of a key, whereupon a spring-driven hammer strikes from behind. As a result, the paper is preloaded into a cylindrical holder, behind the platen, and unrolls up and out when one types. The Martin Howard Collection
