English: Photo of prototype typewriter invented by Christopher Latham Sholes, Carlos Glidden and Samuel W. Soule between 1868 and 1873, and manufactured as the 'Sholes & Glidden Type-Writer' by Eliphalet Remington & Sons Co., Ilion, New York, USA, beginning 1874. This was the first typewriter to be a commercial success (about 5000 were made), the first to use the QWERTY keyboard layout invented by Sholes, and the first to be called a typewriter; the term was coined by Sholes. The source does not say which of the many prototypes this is. Since it is dated the year Remington bought the rights, and was in the Buffalo Historical Society museum near the Remington headquarters, it may be the one Sholes and Glidden demonstrated to Remington. Caption text: "Sholes typewriter, 1873 (Museum, Buffalo historical society)" Alterations: removed frame, caption. Note: As the R is on the place it is nowadays, this is a model modified by Remington. There used to be a period on that spot. (see David, 1985, 'Clio and the Economics of QWERTY', pp. 333)
