Further scrutiny lessens doubts on Bush memos
Some skeptics now say IBM typewriter could have been used
After CBS News trumpeted newly discovered documents Wednesday that referred to a 1973 effort to "sugar coat" President Bush's service record in the Texas Air National Guard, the network almost immediately faced charges that the memos were forgeries with typography that was not available on typewriters used at that time.
But specialists interviewed by the Globe and some other news organizations say the specialized characters used in the documents, and the type format, were common to electric typewriters in wide use in the early 1970s, when Bush was a first lieutenant.
Philip Bouffard, a forensic document examiner in Ohio who has analyzed typewritten samples for 30 years, had expressed suspicions about the documents in an interview with the New York Times, one in a wave of similar media reports. But Bouffard told the Globe Friday that after further study, he now believed the documents could have been prepared on an IBM Selectric Composer typewriter available at the time.
Analysts who have examined the documents focus on several facets of their typography, among them the use of a curved apostrophe, a raised, or superscript, "th," and the proportional spacing between the characters -- spacing that varies with the width of the letters. In older typewriters, each letter was allotted the same space.
