Corona Model 3 'Folding Corona' typewriter. In excellent condition, tested and working. This machine was produced in 1935 in Groton, New York (serial number V687966). The Corona Model 3 is a very small machine that was even more portable thanks to its unique folding mechanism. It was the first typewriter that could be folded. A peculiarity of the Corona 3 is the absence of a fourth bank to minimize dimensions. Therefore, the machine has a double shift for capital letters and numbers. The "Folding Corona" was one of the most popular typewriters of its time, used by Ernest Hemingway and other famous writers. Includes original wooden case.
