Production and public sales began 1895-96. One of the first truly portable typewriters with a full keyboard; this example has the QWERTY keyboard, which was only available on request. Uniquely, this has an interchangeable type cylinder with a then unusual striking method, not seen again until the IBM Selectrix nearly 70 years later.6 3/4" x 12 3/4" x 9 1/4" case.
