Back when I bought the IBM WheelWriter 6 at the junk shop for five francs, I also got myself a Brother LW-30 typewriter word processor (also for five francs).

I picked up what appears to be an internationalised IBM WheelWriter 6 for five francs at a local Zürich junk shop; originally I wanted it for the keyboard but it turns out to be in perfect working order. (Curses.) I made a video. (Now in full HD 60fps — I have a new camera!)
