Style One: This is the oldest style of Japanese-made portable typewriters. Designed in 1959 by Akio Kondo, and called the Brother typewriter, it was the longest-lived style--production of it ended in 1990. The typewriter below is a 1970s version of this design.
Style Two: This style of portable typewriter is based on that of the Brother typewriter, but is more angular. It was designed by G-K Design, of Tokyo, Japan.
