Post-Script: Finding this machine was a pleasant surprise. Finding it for $8 was even better. And finding out that, after being serviced, it types remarkably smooth and clear was an added bonus. This initial round of typing impressed me even more, especially the smoothness of the carriage return, as it uses a peculiar design of tubular bearing housing with radial ball bearings mounted inside a large diameter tube.
