been produced with a mechanical typewriter using proportional letterspacing in the early 1970s. At the time the documents were purportedly created, the matching letterspacing could only have been produced using phototypesetting or hot-metal printing. Since it is not a realistic possibility that Killian would have had these documents printed, Phinney concludes that they are almost certainly modern forgeries. Phinney has long offered $1,000 "to anybody who can produce an office-level device that was available in 1972 that can replicate the relative line endings of those memos" but no-one has ever tried to do that. Desktop magazine in Australia analysed the documents in its November 2004 issue and concluded that the typeface was a post-1985 version of Times Roman, rather than Times New Roman, both of which are different in detail to IBM Press Roman. Inter-character spacing Joseph Newcomer, who helped pioneer electronic typesetting and word processing software, claims that the memos display a simple alternative to kerning characteristic of TrueType fonts but not available on any office equipment in 1972. For example, in words containing "fr", TrueType moves the "r" left to tuck it in under the top part of the "f". The Weekly Standard called Newcomer's explanation the "definitive account" of why the documents were "necessarily forgeries." The Washington Post quoted Newcomer in an article regarding questions about the authenticity of the papers. Centered headers Creating centered headers is possible on a typewriter, even if the font is proportional. The typist can left-justify the header and then use the space bar to count the number of spaces from the end of the text to the right margin. In addition, the IBM Executive and Selectric have a kerning key that would give a more accurate measure of the whitespace. Once this number is determined, halving it gives the number of leading spaces for a centered header. The same centering will be achieved on different occasions if the paper is inserted flush to the paper guide, and the same count of spaces is applied. For an example of multiple centered lines produced using a proportionally spaced typewriter font, see the third page of the contemporary annual history of Bush's Alabama guard unit. Word processors, by contrast, center text based on a computer algorithm using a fixed central reference point rather than the left margin on the typewriter as measured from the paper's edge. If the paper in a printer is flush
