THE UNDERWOOD NO. 3: featuring an early shifting carriage for capitalization, the Under-wood served as Rons first typewriter. The earliest stories from his freshman year at George Washington University bore the stamp of this machine, as did the manuscripts from Encinitas, California where he initially started out writing for the pulps, writing the best I knew.
REMINGTON NOISELESS PORTABLE, a.k.a. Super Seven: according to Robert Heinlein, it was upon this Remington Noiseless Portable (en route from New York City by train) that Ron revised his legendary Fear. The Heinlein remark is, of course, apocryphal, but Rons Super Seven most definitely saw a lot of mileage.
