1933 International Type 31 Serial # n/a 1933 International Type 31 typewriter, Serial # n/a Guillermo Fernandez Boan's 1933 International Type 31 typewriter. 2017-06-18 From the Virtual Typewriter Collection of Guillermo Fernandez Boan: 1933 International Type 31 Serial # n/a According to the IBM Archives, "Alphabetical duplicating keypunches recorded alphabetic Iin tabulating cards so that complete words and names, together with numerical data, could be later printed by an alphabetical accounting machine.
The Type 31 Alphabetical Duplicating Punch was introduced by IBM in 1933, and it automatically ejected one card and fed another in 0.65 second. These machines were equipped with separate alphabetical and numerical keyboards.
The alphabetical keyboard was similar to a conventional manual typewriter except that the shift, tab, backspace and character keys were eliminated, and a skip, release, stacker and '1' key were provided."
According Greg Fudacz (from whom I get this one) "This machine was built by IBM on the frame of an Underwood F-Model portable typewriter".
