Kidder began collaborating with Charles Carrol Colby, a Stanstead, Quebec Canadian investor and promoter, in 1896 to develop a noiseless typewriter using the "pressure print theory". Colby previously had promoted the Wellington overseas and established successful manufacture of that design with Empire in the U.K., and Adler in Germany. Between 1896-1903 Kidder and Colby worked mainly on other commercial ideas like pneumatic saws, bark-scrapers and even a brief flirtation with automobiles, forming the Kidder Motor Vehicle Company, building steam motors in New Haven, CT. before failing in 1903. After 1903, Kidder returns to the noiseless typewriter idea, but Colby is in poor health and suggests Kidder find a new partner. Kidder then partners with Buffalo, NY buisnessman George Matthews and W. C. Ely, who fund the creation of Parker Machine Company. After the sale of Noiseless to Remington in 1924, Kidder attempts one last design before his death; the tiny Rochester. Platen Diameter: unknown, Composition: Steel, without rubber covering. Serial Number Location Standard: On a plate, right side, top under right end of carriage. Portable: on outside of rear frame, at bottom, center. Ribbon/Inking Standard: bichrome 1/2" ribbon. Portable: single-color 7/16" ribbon. Serial Number Location: Standards: On plate on right side top, under right end of carriage. Portables: On outside of rear frame, at bottom center.	5,6,27, 31,59,61, 65,109
