"The Gilman Type Writer" may have been invented by the team of Willard Herbert Gilman and Daniel E. Kempster who were also involved with the creation of the Boston typewriter. The Gilman may have been produced in Maine where Herbert Gilman ran a manufacturing company. The sole sales agent for the Gilman was a man named Stiles Frost of Boston, Massachusetts. I have to admit, the Gilman does appear to be a no-frills Boston.
